Machine learning for microwave radiation based remote and obscured bio-sensing

报告

主要观点

Non-invasive measurement and sensing of vital bio-signs, such as respiration and cardio-pulmonary parameters, have become essential tools in the evaluation process of a subject physiological condition. The demand for new enabling technologies that facilitate remote and non-invasive techniques for such measurements continues to grow. While previous research has made strides in continuous monitoring of vital bio-signs using laser, in this presentation we introduce a novel technique for remote non-contact measurements based on radio frequency. We utilize microwave radiation at e.g. 18GHz and use machine learning algorithms to measure the vital bio-signs of the illuminated subjects by analyzing the changes in the generated back reflected microwave speckles. Unlike laser-based methods, this innovative approach offers the advantage of penetrating through walls and tissues, enabling the measurement of respiration and heart rate. Diverging from traditional radar systems, our method introduces a unique sensing concept that enables the detection of micro-movements in all directions, including those parallel to the antenna surface. The ability to penetrate barriers such as walls and tissues opens new possibilities for remote monitoring in various settings, including home healthcare, hospital environments, and even search and rescue operations.

AI-Driven Multimodal Sensing and Fusion ---Opportunities and Challenges

报告

主要观点

Considering the differences and complementarity among various sensors, multimodal perception has increasingly become a trend in Earth observation remote sensing and industrial automation. With the continuous development of AI technology, multimodal fusion has evolved from simple data-level, feature-level, and decision-level fusion into new modes of cross-modal and cross-domain fusion. This will cover how to fully leverage these new modes to achieve effective multimodal fusion, leading to successful applications in different sensing and vision tasks. Specific application examples include traditional fusion in ocean remote sensing, such as sea ice segmentation and offshore energy facility detection and measurement, as well as tasks like change detection and anomaly detection under cross-modal and cross-domain fusion based on deep learning models, and industrial automation. Finally, related challenges and future research directions are further analyzed and discussed.

On laser light propagating in free space at a speed slower than the speed of light: The case of Bessel-Gauss beams

报告

主要观点

Ten years ago, it has been demonstrated experimentally (with quantum interference experiments using the Hong-Ou-Mandel effect) and theoretically (using an angular spectrum decomposition) that laser light propagates in free space at a speed smaller than the speed of light. As a consequence, a new effect has been demonstrated, namely the fact that an ultrashort pulse propagating in free space should be broadened by a certain amount of time. In the case of Gaussian beams, such broadenings have been found to be too small for an easy experimental demonstration. A typical value for such a broadening was equal to 100 femtoseconds, and has been found to be too small for an easy measurement and even for an easy detection. Ideal Bessel beams would allow arbitrary large broadenings, but such beams are unphysical because they carry an infinite amount of energy. This leads to the idea that Bessel-Gauss beams, which can be viewed as ideal Bessel beams with a Gaussian apodization which makes them physical, should allow larger pulse broadenings that in the case of Gaussian beams. This idea will be discussed in the present talk and it will be theoretically demonstrated that, indeed, as expected, Bessel-Gauss beams may generate large pulse broadenings, including of the order of the nanosecond.

A Dual-Band Multi-Beam Reflectarray Antenna Based on Polarization Selection Technique for Sub-Terahertz Applications

报告

主要观点

A single-layer-substrate dual-band multi-beam reflectarray antenna based on polarization selection technique is proposed for sub-terahertz (sub-THz) applications in this paper. For the antenna element, two circular rings with grooves and different sizes are orthogonally nesting to each other to yield dual-band characteristics. Notably, a straight-bar microstrip line is used to combine both ends of the small-size ring, yielding Y-polarized selection feature, whereas a pair of arc-shaped phase shift lines are attached to the outer of the large-size ring, forming X-polarized selection characteristic. Furthermore, the digital coding metasurface together with the single- and multi- focus phase compensation techniques are separately adopted to realize the four-beam radiation and dual-beam scanning radiation in the lower and upper frequency bands for the antenna array. Measured results show that a wide separated elevation angle of up to 104◦ and a high aperture efficiency of 49.2% are obtained at the lower frequency of 135 GHz, while a low scanning loss of 1.6 dB and another high aperture efficiency of 29% are realized at the upper frequency of 170 GHz. Additionally, high peak gains of 19.7 dBi and 26.3 dBi are also achieved for the dual bands, respectively. Therefore, it might be a potential candidate for the future 6G point-to-multipoint large-capacity, wide-coverage and high-resolution scanning communications.

Hyperspectral remote sensing, AI and important Earth Observation applications

报告

主要观点

Over the next decade, hyperspectral (HS) satellite imagery is expected to move from being a specialized research tool into a mainstream geospatial capability that underpins generic remote sensing applications such as environmental monitoring, precision agriculture, resource management, and even national security. The evidence is everywhere. With newly launched and slated HS satellite missions, both public and private, indicating confident investments of billions. For Earth Observation applications, the new commercial products are targeting constellation of satellites, at high spectral resolution (5 nm), high spatial resolution (5m) and high temporal resolution, for some application such as GHG monitoring some expected daily. In general, optical HS wavelengths at full stretch spans 400 nm to 2500 nm. Publicly available HS data (e.g. PRISMA, EnMAP) are acquired at 30m which limits its use of many potential applications. To mitigate this limitation, researchers rely on image enhancement methods such as fusion/pan sharpening, spatial super resolution, and more recently spectral super resolution via Sparse Theory and Deep-learning based methods. Airborne including aircraft and drone-based HS data is also becoming conventional for a broad range of applications such as habitat mapping and biodiversity research. Fused with thermal and lidar data makes it powerful data resource. It serves as the base for ground truth references and evaluation for spaceborne products. Under the context of robust AI, I will discuss some recent development in EO HS data, and collaboration experience in environmental-AI topics (e.g. natural disasters, marine ecology), as well as the challenges and relevance of HS remote sensing and AI.

Bioengineered Apoptotic Bodies for Trauma Brain Injury Therapy

报告

主要观点

Microglia modulation plays an essential role in the treatment of trauma brain injury (TBI), whereas mesenchymal stem cells (MSCs)-derived apoptotic bodies can modulate the microglia in a natural process. In this study, a TBI therapy platform based on bioengineered apoptotic bodies derived from MSCs (ALP) were constructed to stimulate natural MSCs apoptosis, modulate microglia to release anti-inflammatory factors, and promote neuronal proliferation. ALP was prepared by chimeric integration of membrane proteins of apoptotic bodies (ApoM) with gastrodin and Cy5-loaded liposomes. In particular, ALP can actively target microglia and neurons while both gastrodin and ApoM components can inhibit the activation of NF-κB signaling pathway in microglia. Meanwhile, gastrodin can be released into the high reactive oxygen species (ROS) microenvironment to stimulate neuronal proliferation, whereas ApoM can stimulate the microglia that are switched into M2-phenotype to release inflammatory factors and neurotrophic factors. Both in vivo neurobiology and behavior studies demonstrated that ALP can effectively alleviate inflammation, improve cognitive and motor functions, and enhance the metabolic activity in TBI mice. This study offers a novel strategy to effectively stimulate the immune response of microglia for the recovery of brain injury. To the best of our knowledge, this is the first study to inspect the biological mechanism and therapeutic efficacy of MSCs-derived apoptotic bodies for TBI.

Towards Robust and Reliable Fourier Ptychographic Microscopy for High-Resolution, Large Field-of-View Biomedical Imaging

报告

主要观点

Fourier Ptychographic Microscopy (FPM) has emerged as a transformative computational imaging technique that overcomes the classical trade-off between resolution and field-of-view (FOV). By synthesizing a high numerical aperture from multiple angle-varied illuminations, FPM enables high FOV, high-resolution, and quantitative phase reconstructions at relatively low hardware cost. Yet, despite its promise, widespread adoption has been hindered by barriers in usability, calibration complexity, and the fundamental challenge of incomplete phase recovery. To address accessibility, we developed the FPMapp, an open-source, intuitive graphical user interface designed to make FPM reconstruction available not only to experts but also to non-specialist users. Built on a Quasi-Newton reconstruction engine, the software incorporates GPU acceleration, background suppression, noise reduction, and robust misalignment correction. By lowering the computational and technical entry barrier, FPMapp significantly broadens access to FPM, enabling high-quality reconstructions even on standard brightfield microscopes equipped with LED arrays. For reliable experimental performance, we further introduce the Automatic LED Calibration (ALC) method. This sample-agnostic, two-step calibration procedure corrects translational misalignments using Fourier spectrum symmetry and compensates rotational errors through subpixel registration. Unlike model-heavy or phantom-based approaches, ALC is simple, fast, and easy to implement, making it equally suitable for non-experts seeking robustness and for experts requiring precision in demanding experimental scenarios. From a metrological perspective, a persistent limitation of FPM lies in its inability to accurately retrieve low spatial frequency phase information, due to the absence of phase encoding in brightfield illuminations. To overcome this, we propose a hybrid FPM+TIE approach. By augmenting the standard FPM dataset with just a single defocused on-axis image, the Transport of Intensity Equation provides the missing low-frequency content, which is seamlessly combined with the high-frequency information from FPM. This simple yet powerful addition yields broadband, quantitative phase reconstructions with enhanced fidelity across spatial frequencies. By integrating open-source reconstruction, robust calibration, and hybrid phase retrieval, we establish a framework that makes FPM both more accessible and more reliable, paving the way for its broader application in biomedical imaging, digital pathology, and optical metrology.

Human Pose Estimation for Individuals with Limb deficiencies

报告

主要观点

Human pose estimation aims to predict the location of body keypoints and enable various practical applications. However, existing research focuses solely on individuals with full physical bodies and overlooks those with limb deficiencies. As a result, current pose estimation annotation formats cannot be generalized to individuals with limb deficiencies. In this work, we introduce the Limb-Deficient Pose Estimation task, which not only predicts the locations of standard human body keypoints, but also estimates the endpoints of missing limbs. To support this task, we present Limb-Deficient Pose (LDPose), the first-ever human pose estimation dataset for individuals with limb deficiencies. LDPose comprises over 28k images for approximately 100k individuals across diverse limb deficiency types and ethnic backgrounds. The annotation process is guided by internationally accredited para-athletics classifiers to ensure high precision. In addition, we propose a Limb-Deficient Loss (LDLoss) to better distinguish residual limb keypoints by contrasting residual limb keypoints and intact limb keypoints. Furthermore, we design a Limb-Deficient Metric (LD Metrics) to quantitatively measure the keypoint predictions of both residual and intact limbs and benchmark our dataset using state-of-the-art human pose estimation methods. Experiment results indicate that LDPose is a challenging dataset, and we believe that it will foster further research and ultimately support individuals with limb deficiencies worldwide.

A presentation of experimental Digital In-line holographic configurations for 3D velocity/size measurement of particles in fluids

报告

主要观点

Digital in-line holography (DIH) is well adapted to diagnostics in complex installations where optical accesses are not easy. Generally, it can be said that for a given situation where classical transmission imaging is feasible, in-line holography can also be applied. The reconstruction process of holograms is straightforward because a simple propagation equation (Fresnel Integral) is needed to process the 2D fringe pattern in order to recover the whole 3D volume to be investigated. Moreover, it is now well admitted that, under this configuration, the requirements concerning the coherence degree of the illuminating wave are very low and the use of light sources such as laser diodes or femtosecond lasers is even recommended for improving the signal-to-noise ratio of the reconstructed images. Under some particular situations (elliptic recording wave for example), more sophisticated algorithms can be used to improve the reconstruction process. For all these reasons, DIH is particularly interesting for diagnostics in flows where size, location, velocities or trajectories of particles have to be measured. Several examples of configurations are given for various applications such as near-wall velocity measurements for the characterization of a boundary layer, droplet sizing in a nuclear power plant, extraction of 3D trajectories of particles in a vortex and characterization of a moving droplets during the stretching of a viscoelastic filament.

Shape measurements at high resolution using digital holographic microscope

报告

主要观点

Digital holographic microscopy is a suitable measurement technique for non-contact, short measurement time, and highly accurate surface characterization of optical and mechanical components. This work will present challenges and research results related to the development of measurement techniques enabling characterization of continuous and non-continuous surfaces by using Digital holographic microscopy. The continuous surfaces reconstruction algorithm, which enables accurate shape reconstruction, will be discussed. Then, for the same type of object system modification, including the super-resolution concept and point source illumination, will be presented. For both presented solutions, system implementation and new shape reconstruction algorithms will be shown. For the measurement of non-continuous surfaces, the Digital holographic microscopy is referred to as Digital Holographic Profilometer. This method is based on a scanning approach where measurement is performed from a set of holograms captured, and then the result is obtained by constructing the Longitudinal Scanning Function, which, after analysis, results in the measured shape. Five developments of Digital Holographic Profilometer will be discussed: (i) Plane wave scanning, (ii) Single shot method, (iii) Plane wave scanning for High NA measurement, (iv) Spherical wave scanning for Extreme NA measurement, and (v) high resolution measurement using structured illumination. The last discussed approach presents primary research results, while the other ones show results of published research.

Characterization of ice particles using interferometric particle imaging

报告

主要观点

Interferometric Particle Imaging enables to measure the size of sub-millimetric particles with a relatively large field of view, at a working distance that can reach tens of centimeters. It is thus well adapted to meteorology applications where the concentrations in particles are not too high. While the interferometric images of droplets are two-wave interference patterns, the interferometric images of ice particles are speckle patterns. The properties of the speckle are mathematically linked to the shape of the particle.

This talk will present the development of this measurement method, from the establishment of principles and models to their validation in laboratory (freezing columns, icing wind tunnel) and in-flight tests. The analysis of the speckle patterns is a fundamental point in order to perform accurate measurements. Image processing methods involving phase-retrieval algorithms or neural networks will be presented and the results obtained will be discussed. In a second part, we will focus on the limits of the method: overlapping of interferometric patterns, sampling conditions, sizing limits. The last study will be in particular devoted to the estimation of the low-sizing limit. Using the Discrete Dipole Approximation, we will calculate the exact interferometric images of ice particles whose shapes are rigorously predicted using phase-field modelling. Results will enable to quantify rigorously the limits of the technique, when the size of ice particles can be less than ten micrometers.

报告

主要观点

Recent advances in optics and machine learning reveal a gap between camera limitations and AI-enhanced image reconstruction. Many methods produce visually plausible results that contradict physical optics, risking inaccurate spectral or spatial data. We introduce a physics-informed GAN for super-resolution in optoelectronic perception. Camera-specific priors—PSFs, MTFs, spectral responses—are embedded in both generator and discriminator. The generator uses PSF-conditioned deblurring, residual-attention blocks, and pixel-shuffle upsampling. The discriminator enforces physical consistency in blur and edges. Training combines adversarial loss with spectral unmixing accuracy and explainability via SHAP gradients. The model generalizes across cameras without recalibration, avoids hallucinations, and provides confidence maps. It achieves fast inference while maintaining physical accuracy, benefiting applications from remote sensing to autonomous navigation.

Unconventional Superconductivity and Optical Signatures of Highly-doped Graphene

报告

主要观点

Recent advances in intercalation have enabled ultra-high doping in graphene, shifting the Fermi level near extended van Hove singularities and enhancing electronic interactions. This regime is a fertile ground for unconventional superconductivity. Building on our theoretical framework for superconductivity in graphene, we develop effective tight-binding models that incorporate superlattice potentials and dopant-carbon hybridization, reproducing key features observed in photoemission, such as folded π-bands and high-order van Hove singularities. We also compute optical signatures that can help identify superlattice symmetry and emergent phases in experiments. In this talk, I will present these results alongside recent developments in twisted and untwisted graphene multilayers, where similar mechanisms may give rise to superconductivity. Together, these systems offer a unified perspective on correlation-driven phases across different graphene-based platforms.

Ultra-Wideband Wide-Angle-Scanning Phased Array Antennas for Integrated Sensing and Communications and 6G NTN

报告

主要观点

The past decades saw rapid development of wireless communications, radar sensing and imaging systems using more and more frequency bands. Future generations of wireless systems will require the integration of multiple functions, e.g. communications, sensing, imaging, navigation and wireless power transfer, etc, into one single system. In the meantime, future communication networks will see the seamless integration of terrestrial networks and non-terrestrial networks (NTN) using Uncrewed Aircraft Systems (UAS), High Altitude Platforms (HAPs) and satellites in low-earth orbit (LEO), Medium Earth Orbit (MEO), Geostationary Earth Orbit (GEO) and Highly Elliptical Orbit (HEO). Innovations in phased array antennas are critical for the success of these future wireless systems. In particular, the phased array antenna is expected to be capable of operating over an ultra-wideband frequency range and achieving wide-angle beam scanning while having a low profile, compact size, low power consumption, low complexity and low cost. Hence there are lots of challenges to be overcome in the field of phased array antennas. This invited talk will provide an overview of state-of-the-art development in ultra-wideband wide-angle beam-scanning phased array antennas using tightly coupled arrays (TCA). TCA has become a very popular technique for realizing ultra-wideband wide-angle beam scanning phased array antennas. Some recent examples will be discussed. Future challenges will also be discussed at the end of the talk.

2D and 3D lensless holographic microscopy

报告

主要观点

Lensless holographic microscopy is an emerging imaging modality that enables quantitative phase imaging across an exceptionally large field of view (even exceeding 100 mm²) while maintaining a micrometer-scale resolution (typically ~1–2 µm). By eliminating conventional lenses, this technique significantly reduces system complexity, size, and cost, making it highly suitable for compact, scalable imaging platforms. In this work, we present a comprehensive overview of numerical strategies employed to enhance phase retrieval accuracy in lensless in-line holography. We explore algorithmic approaches aimed at improving signal-to-noise ratio and spatial resolution, including multi-height and multi-wavelength phase recovery. Furthermore, we address challenges related to 4D sample localization, where both spatial and temporal dynamics of the sample are reconstructed from 2D holographic measurements. Finally, we extend the lensless microscope to a lensless tomographic platform, demonstrating 3D reconstructions of volumes exceeding 25mm3 (with exceptional over 1 mm depth), highlighting the system’s potential for high-throughput biomedical or environmental monitoring applications. Our findings underscore the potential of computational techniques to push the limits of lensless holography, paving the way for real-time, wide-field, volumetric imaging in resource-constrained settings.

Diffraction gratings aided common-path optical diffraction tomography

报告

主要观点

Optical Diffraction Tomography (ODT) is a label-free imaging technique that enables non-invasive, 3D reconstruction of the refractive index (RI) distribution in transparent and semi-transparent microscopic samples, such as biomedical cells and tissue fragments. To reduce coherent noise and achieve high-fidelity tomographic reconstructions with a high signal-to-noise ratio, ODT is ideally implemented using a common-path interferometric configuration combined with low-coherence illumination. It has been shown that the standard tomographic reconstruction algorithm, originally developed for fully coherent illumination, remains valid under partially coherent illumination. Thus, reducing coherence improves the signal-to-noise ratio without compromising reconstruction accuracy. However, a challenge arises from the use of common-path architectures, which often employ shearing interferometric setups. In such systems, the interference pattern is formed by the superposition of two transversely shifted copies of the object beam, resulting in measurements of phase derivatives rather than absolute phase. Until recently, tomographic reconstruction in this context required numerical integration of the shearing phase maps to recover the full phase information prior to applying reconstruction algorithms. This step was cumbersome, error-prone, and required two separate derivative measurements in orthogonal directions. Recent work has addressed this limitation through the introduction of Gradient Optical Diffraction Tomography (GODT). GODT enables direct reconstruction of the 3D distribution of the RI derivative from a tomographic stack of shearing interferometry data, offering new imaging contrast with increased sensitivity. The algorithm has a strict theoretical foundation based on the first-order Rytov approximation within Wolf’s diffraction theory [5], ensuring its physical rigor and reliability. GODT requires both phase and amplitude inputs, similarly to conventional ODT methods. While the shearing phase is directly accessible via shearing interferometry, the corresponding amplitude is not. This missing information is recovered using supervised deep learning, enabling accurate GODT reconstruction. Together, these advances position GODT as a powerful extension of ODT, expanding its capabilities for high-sensitivity, label-free 3D imaging in complex biological samples.

Cross-Modal Perception: Fusing Optoelectronic and Visual Data with Deep Learning

报告

主要观点

RGB cameras provide rich texture and color information, while infrared (IR) imaging offers robustness under low-light and adverse illumination conditions. Fusing these complementary modalities has emerged as a promising direction for improving object detection and person re-identification (ReID) in unconstrained environments. However, cross-modal perception faces significant challenges due to differences in spectral properties, resolution, and domain-specific noise. In this work, we present a deep learning–based framework for RGB–IR fusion, leveraging attention-guided feature alignment and domain-adaptive embedding strategies. For object detection, multimodal feature fusion improves recognition accuracy in scenarios where single modality inputs fail, such as nighttime surveillance or cluttered urban scenes. For person ReID, we introduce a modality-invariant embedding space that enhances identity consistency across RGB and IR domains, addressing appearance variations caused by lighting and viewpoint changes. Experimental evaluations on benchmark RGB–IR datasets demonstrate that the proposed fusion approach significantly outperforms unimodal baselines, achieving higher robustness and generalization across environments. By integrating the complementary strengths of RGB and IR sensing, our work advances multi-domain perception for security, transportation, and smart city applications, enabling reliable cross-modal detection and identification in real-world conditions.

Nonlinear control of structured light

报告

主要观点

Harnessing all degrees of freedom of light for a purpose, called structured light, has unlocked a suite of innovations across fields ranging from quantum communications to neural networks. When exposed to sufficiently intense light, nonlinear effects emerge, unleashing new mechanisms to control light’s structure. Traditionally such control has been achieved using tools relying on linear light-matter interactions, where modifying the material’s thickness or orientation enables the generation of light patterns. In contrast nonlinear optics allows us to control light with light itself, allowing us to structure multiple degrees of freedom (DoFs) of light. Here we introduce a novel approach to tailor both amplitude and phase of light. Combined with digital holography technique, this allowed us to diffract, correct and even detect light. It was achieved by structuring light with light itself, enhancing the frequency conversion fidelity beyond 90%. By leveraging these virtual light-based patterns, we further enhance the frequency conversion efficiency by more than 40%. While frequency conversion enables pattern creation across different wavelengths, high-fidelity detection is essential to extract the encoded information. We address this by introducing a nonlinear version of modal decomposition, allowing us to unravel information in the near-infrared wavelength using a basis encoded in the visible wavelength. With full control over both the creation and detection of structured light, we further deployed our system in a prepare-and-measure configuration over an aberrated optical channel. Remarkably, the phase conjugation inherent to nonlinear process allowed us to naturally correct for distortions at the speed of light, without the need for active measurements. We believe that our nonlinear framework for structured light unlocks powerful new capabilities, paving the way for future breakthroughs in optical communication, imaging, and spectroscopy.

Full analytical description of the remodeling of a “frozen wave”-type structured beam after an arbitrary number of pair of lenses for light scattering applications

报告

主要观点

This talk will discuss mathematical aspects related to analytical descriptions of a specific class of non-diffractive beams after passing through an arbitrary number of pairs of optical lenses (4f systems). Such beams — known in the literature as "Frozen Waves" (FWs) — are constructed through specific and discrete superpositions of Bessel modes (or beams) of the same frequency. In this work, a paraxial regime is assumed in which a scalar treatment is fully justified. The rationale for this work is to allow to subsequently express the magnified/demagnified field pattern observed in recent experiments on optical trapping of micrometric particles in holographic optical tweezers, and in continuous depth optical holography for two- and three-dimensional imaging, within a formalism known as Generalized Lorenz-Mie Theory (GLMT) for spherical and homogeneous scatterers. In addition to these applications, FWs are expected to be incorporated as trapping or illumination beams in several interesting applications, such as optical trapping displays based on photophoretic forces and thermal imbalance, virtual and augmented reality, optical imaging, remote sensing and alignment of optical systems, and the fabrication of optical nanochannels in glass, among others. The results obtained in this work, when compared with those observed experimentally using one, two or more pairs of lenses, allow us to fully validate the present approach, and future work can explore it to obtain a complete description in the GLMT, in terms of the beam shape coefficients (BSCs) of the output optical field, which is a reshaped version of the original beam after an arbitrary number of lenses.

Complex-time dynamical processes in tunneling

报告

主要观点

Attosecond dynamics is a frontier research direction in the field of strong-field atomic and molecular physics, with its core aim being to reveal the microscopic mechanisms of tunneling ionization and the resulting attosecond electron dynamics in atoms and molecules under intense laser fields. Real-time tracking and imaging of ultrafast electron dynamics are essential approaches for understanding and exploring photophysical, photochemical, and photobiological processes. In this work, we employ a quantum-trajectory method that incorporates sub-barrier Coulomb interactions to investigate the complex-time dynamics of tunneling ionization of atoms and molecules in strong laser fields, thereby uncovering the influence of sub-barrier interactions on attosecond angular streaking measurements and on resonance-enhanced ionization in molecules.

Non-perturbative perspective of atomic resonance ionization in intense laser fields

报告

主要观点

Within the framework of scattering matrix theory, we have developed a quantum model for resonance ionization of atoms via Rydberg states in strong laser fields, namely the Freeman resonance ionization process. Computational analysis reveals that this process exhibits new non-perturbative features that differ from the conventional picture of direct ionization from the ground state into dressed continuum states, where the final electron angular distribution corresponds to the number of absorbed photons. Instead, this process involves multiphoton transitions between dressed states. Because dressed states contain components with different angular momenta, the transitions no longer correspond to definite changes in angular momentum. The angular distribution of the final-state electrons is determined by the interference between different multiphoton transition pathways and by the angular distribution of the resonant Rydberg states.

Berry phase in laser–solid interactions

报告

主要观点

In quantum mechanics, a quantum wave packet may acquire a geometric phase when it evolves along a periodic trajectory in parameter space. In condensed matter systems, the Berry phase plays a crucial role in fundamental phenomena such as the Hall effect, orbital magnetism, and polarization. Elucidating the quantum nature of these processes often requires highly sensitive quantum techniques, such as tunneling, which is the dominant mechanism in scanning tunneling microscopy and tunneling transport devices. In this work, we integrate the two key phenomena of geometric phase and tunneling, and observe a complex-valued Berry phase through strong-field light–matter interactions in solids—a phase that was theoretically predicted by M. Berry more than three decades ago. By employing attosecond-precision control of tunneling barriers, we experimentally measured the imaginary part of the Berry phase accumulated by electrons during tunneling within subcycles of the optical field. Simulations based on semiconductor Bloch equations accurately reproduce the experimental results and support the underlying physical interpretation. This study opens new theoretical and experimental directions for the physics of geometric phases and their realization in condensed matter systems, and extends strong-field optical metrology in solids to the exploration of topological quantum phenomena.

Extreme Ultraviolet Optical Frequency Combs and Their Applications

报告

主要观点

As a product of the ingenious combination of femtosecond optical frequency combs and strong-field high-order harmonic generation, the extreme ultraviolet (XUV) optical frequency comb—abbreviated as the XUV frequency comb—is currently the only tabletop coherent light source in the XUV region with a linewidth reaching the kilohertz level. It has significant applications in precision measurement, attosecond physics, and ultrafast control of matter. Since 2016, we have been independently developing the XUV frequency comb and have overcome several key technical challenges, including high-precision locking of the repetition rate and carrier-envelope offset frequency of high-power femtosecond lasers, kilowatt-level femtosecond enhancement cavities, and efficient intracavity high-order harmonic generation and output coupling. These advances enabled us to successfully realize the first domestically developed XUV frequency comb system in China. Based on the high-repetition-rate (~100 MHz) femtosecond laser provided by this system, we have carried out research on strong-field ultrafast physics under extreme conditions. By combining spatial light-field control of femtosecond laser pulses with cavity enhancement techniques, we realized vortex ultraviolet frequency combs. With the aid of supersonic molecular beam preparation, we further achieved precision spectroscopy of atoms and molecules in the vacuum ultraviolet region. In the next stage, we will continue to enhance the overall performance of the XUV frequency comb and advance its major scientific applications in the field of precision measurement.

This report presents our study on the photodesorption processes of atomic anions (H⁻ and I⁻) and molecular anions (SF₆⁻) in ultrafast laser fields, based on a home-built mass-selected negative ion source combined with a time-of-flight mass spectrometer/electron velocity imaging detection system. By measuring the desorption yields, as well as the kinetic energy and angular distributions of desorbed photoelectrons under various ultrafast laser fields, and combining these results with theoretical calculations, we have revealed in depth the physical mechanisms and partial-wave interferences involved in multiphoton desorption, above-threshold desorption, and two-electron desorption channels of anions. For molecular anions, we further explored the roles of molecular orbitals and excited-state resonances in the desorption process.

High-order harmonic generation (HHG) in gases is an important approach for producing ultrashort attosecond pulses. Owing to the relatively low conversion efficiency, further investigations of the harmonic emission process are required. The complexity of the HHG process poses significant challenges for rapid theoretical simulations. By applying machine learning schemes such as time-series analysis and neural networks, we have substantially improved the computational efficiency of high-order harmonic generation.

Approximate solution and application of periodic driven two-level system

报告

主要观点

By utilizing the complete solution of time-invariant solutions, the first-order approximate solution for a two-level system under periodic driving is obtained, providing analytical expressions applicable to degenerate, near-degenerate, and non-degenerate conditions under weak coupling. Comparison with numerical results from Floquet theory reveals that the approximate analytical expressions agree well with numerical results over a considerable range. This demonstrates the validity of the perturbation method under time-invariant conditions. The importance of the system's translational symmetry is emphasized: in the absence of coupling, the instantaneous eigenstates of Floquet have analytical expressions, where the eigenstates are linear superpositions of the original eigenstates modulated by Bessel functions, clearly exhibiting translational symmetry; under weak coupling, the instantaneous eigenstates of the Floquet two-level system still retain translational symmetry; the system's dynamics can be equivalently described as a two-level system of Floquet transient states, also a consequence of translational symmetry. Using this analytical solution, the Rabi oscillation behavior of the system under periodic driving is investigated; under near-resonance conditions, the results align with the Van Vleck (GVV) approximation; the asymmetry of the Rabi spectrum under periodic driving is also discussed. This provides an effective method for a deeper understanding of Floquet phenomena.

Coherent emission and attosecond absorption of molecules driven by strong laser fields

报告

主要观点

Strong field ionization (SFI) of molecules prepares the ions in coherent yet exotic exaction states which manifest extraordinary emission and absorption properties. In this talk, we present theoretical and experimental explorations of the multi-dimensional dynamics of atoms driven by strong laser fields, from SFI of the neutral, multiphoton excitation of the ion to coherent emission. We show that coherent supercontinuum can be generated in either the ultraviolet for molecules or EUV region for noble gas atoms. With the state-of-art attosecond transient absorption spectroscopy, we demonstrate that the subcycle dynamics and the quantum coherence can be probed in attoseconds. It is shown that the modulation of the absorbance provides importance clue of the electronic and vibronic coherence as well as the time-delay of resonant absorption of the ions.

Enhancement of Single-Order High-Order Harmonics

报告

主要观点

High-order harmonic radiation is coherent radiation emitted from the interaction between lasers and atoms, with a frequency range extending from visible light to the extreme ultraviolet (XUV) and even soft X-ray regions. It is one of the new-generation approaches to obtaining coherent extreme ultraviolet light sources. The acquisition of single-order high-order harmonics with specific frequencies is of great significance for fields such as coherent diffraction imaging.

The Process of Single-Photon Compton Scattering of Bound Electrons in an Intense Laser Field

报告

主要观点

We develop the strong-field frequency-domain theory to study the single-photon Compton scattering process of bound electrons in a high-frequency intense laser field. We discover and explain the phenomenon that, with the increase of incident photon energy, the angular-resolved spectrum of Compton-scattered photons transitions from a symmetric distribution of forward scattering and backward scattering to an asymmetric one. We further advance this theory to investigate the Compton scattering process of positronium.

Hyperbolic Polaritonics with Bulk Optical Crystals

报告

主要观点

Confining the Mid-IR photons (~10 µm) at nanoscale is important to develop Mid-IR nanophotonics. Recent focuses on the phonon polaritons in anisotropic crystals. Such materials can sustain extreme anisotropy, known as hyperbolic responses, to support extremely large momentum, thus confining Mid-IR photons to nanoscale. There are several emerging platforms, including the van der Waals materials. One can further apply the twisted stacking to further design the platforms of van der Waals materials. However, the mass production for practical Mid-IR nanodevices based on them is not available; besides, the propagation distance is limited. Here, I will discuss our recent efforts on study the hyperbolic polaritonic with natural bulk crystals. I will first show how new modes can be sustained in those natural crystals, such as calcite. Herein, the highly confined Mid-IR polaritons can propagate like a ray, in a long distance (~20µm) at the surface of bulk crystals. Moreover, I will show how the crystal symmetry is important to regulate the polaritonic behaviors. Specifically, we will discuss how monoclinic crystal can support the asymmetric propagation of polaritons, due to the necessary non-Hermitian nature of the system, and provide experimental evidence of the system. Our theoretical exploration and experimental efforts would be very important for the mass-producible platforms based on natural bulk crystals for mid-IR nanophotonics and hyperbolic polaritonics.

Reinforced optical cage systems enable drift-free single-molecule localization microscopy

报告

主要观点

Single-molecule localization microscopy (SMLM) achieves nanometer-scale resolution but is compromised by sample drift during image acquisition. We present Reinforced Optical Cage Systems (ROCS), a novel approach that eliminates drift at its mechanical source rather than correcting it through complex image post-processing or fiducial markers. ROCS employs perforated optomechanical components interconnected by tungsten-steel rods in a design proven by mechanical stability simulations. Our ROCS-based microscope demonstrated exceptional stability with mean sample drift of 7 nm over 2 hours in widefield fluorescence imaging and approximately 10 nm over 15 minutes in SMLM, obtaining super-resolution and high-fidelity without the need for drift correction. This framework offers a straightforward, cost-effective, and low-maintenance solution that enhances accessibility to high-performance super-resolution microscopy. By tackling the fundamental issue of mechanical instability, ROCS enables more reliable precision instrumentation for the broader scientific community.

Airy theory improved with uniform approximation and Vectorial Complex Ray Model

报告

主要观点

The classical Airy theory has long served as a foundational framework for modeling scattering diagrams of rainbows of a spherical particle and optical diffraction near caustics in more general cases. However, its accuracy and applicability are limited in regions where rapidly varying phase and amplitude coexist. Many researchers have contributed to the improvement of this situation by different methods: using higher order approximation for phase and amplitude, stretching argument in Airy function and application of uniform approximation, etc. These methods have improved considerably the precision in the prediction of the first order rainbows. But evident discrepancy from rigorous Debye or Mie theory still exists for rainbows of high orders and there is no practical means to predict the scattered field around the caustic regions of a given non-spherical particles like ellipsoids and pendant drops. This talk will give a survey on the evolution of Airy theories and present a method based on the combination of uniform approximation and Vectorial Complex Ray Model (VCRM), which enables precise treatment of both spherical and non-spherical particles. The uniform approximation ensures smooth transitions between lit and shadow regions, removing discontinuities in ray model, while the VCRM incorporates polarization-dependent phase and amplitude corrections, allowing for accurate modeling of high order rainbows. It is expected that this combined approach significantly enhances predictive fidelity, particularly in focal regions and near optical singularities, while retaining computational efficiency.

High-Resolution Carrier Transport and Efficiency Mapping in Semiconductor Devices with Laser Scanning OBIC Microscopy

报告

主要观点

Laser scanning optical beam-induced current (OBIC) microscopy is a powerful, non-destructive technique for high-resolution characterization of semiconductor devices, enabling visualization of active regions, identification of structural defects, and quantification of key parameters such as carrier lifetime and diffusion length. Despite its capabilities, commercial OBIC systems remain prohibitively expensive for many laboratories and often lack the modularity required for experimental customization. In this presentation, we describe the design and straightforward construction of a cost-effective laser scanning OBIC microscope, built entirely from commercially available optical and electronic components and paired with a custom-developed LabVIEW-based control and data acquisition system. The platform integrates a multispectral laser source, a galvanometer mirror scanning unit for rapid raster imaging, precision scan/tube lens assemblies, and an inverted microscope. Hardware control is implemented via a National Instruments PCIe-6351 interface, enabling synchronized beam scanning, photocurrent acquisition, and real-time image reconstruction. The software features flexible scanning patterns (unidirectional, fast-reset, and bidirectional), integrated error handling, and visualization tools, and is architected to support additional imaging modalities such as electroluminescence, polarization-resolved imaging, and fluorescence anisotropy. Preliminary validation was carried out on a silicon PIN photodiode in photovoltaic mode using a 20× objective, achieving a focused spot size of ∼1.22 μm. OBIC imaging produced spatially resolved photocurrent maps and internal quantum efficiency (IQE) distributions, clearly resolving homogeneous active regions as well as non-photosensitive boundaries. The OBIC microscope presented here delivers high spatial resolution and modular expandability, offering a transformative alternative to commercial systems for semiconductor diagnostics, solar cell performance evaluation, and defect analysis. Its adaptability and multimodal compatibility position it as a versatile research tool for both academic and industrial laboratories.
