Abstract ：
Cylindrical vector beams (CVBs) represent a prominent application mode characterized by cylindrically symmetric intensity distributions. In particular, vectorial vortex beams with spatially continuously varying polarization states have garnered significant research attention due to their unique ability to manipulate matter through innovative interaction mechanisms. To generate switchable scalar orbital angular momentum (OAM) and CVB lasers using integrated devices, metasurfaces with liquid crystals (LCs) have emerged as a promising integrated platform with substantial implications for nanophotonics and optical field modulation. The device enables precise control of scalar vortex beams using silicon antennas in a horizontal polarization state. Simultaneously, the orientation of LC molecules can be dynamically switched on or off to form OAM beams in the vertical polarization state, leveraging the polarization-sensitive modulation characteristics of nematic LCs. This approach facilitates two distinct operational modes. First, compensating for the horizontal polarization phase of the silicon antenna to produce a scalar linearly polarized laser, and second, generating vertically polarized vortex light to create a cylindrical vector laser. Our study demonstrates a practical methodology for harnessing switchable scalar OAM and CVB lasers with high-speed responsiveness and exceptional spatial mode diversity. The proposed technique holds considerable potential for advanced applications in 3D optical trapping, communications, holography and related interdisciplinary fields.

Abstract ：
Metasurfaces are artificially intelligent planar optical devices that can realize excellent functions by optimizing the design of nanostructures and arrays. Metasurfaces have become the preferred approach for fabricating integrated and compact optical systems with micro- and nano-scale solutions for realizing multi-dimensional modulated optical devices. Herein, the realization of multi-fold phase holography is demonstrated by combining switchable optical frequencies with hybrid circular and linear polarization states. The original holographic phase distribution can be inversely optimized using an adaptive momentum gradient descent algorithm. Furthermore, completely different images can be reconstructed when the phase values are several times the original values. The multi-fold phase modulation can be achieved by optimizing the structural distribution of the dielectric metasurface with the incident changeable light frequency and decoupled circular and linear polarization. Different polarization combinations enhance the flexibility of multiple holographic modulations. This technology provides new solutions for dynamic multi-fold beam directional refraction and excitation, orbital angular momentum communication, multi-fold holographic displays, optical encryption and camouflage, light switching, and shaping.

Abstract ：
Three-dimensional underwater imaging technology can directly and effectively reflect the morphological characteristics of underwater targets, and plays a key role in underwater target detection, Marine research, and engineering applications. Moreover, in an underwater environment, due to the serious absorption and scattering effects of light waves in the process of underwater propagation, image quality degradation problems such as brightness reduction, contrast reduction, image blur, imaging result resolution reduction and so on are not easy to carry out 3D imaging. Polarization differential ghost imaging can use the polarization properties of light waves to make up for the shortcomings of existing underwater imaging methods, and binocular three-dimensional imaging can obtain more dimensional information, to improve the quality of three-dimensional imaging. Ghost imaging has been proved to have strong anti-interference, and has significant advantages in low light and scattering media. This paper proposes an underwater binocular 3D imaging method based on polarization differential ghost imaging. Our method can better suppress the influence of water scattering on imaging, so that the 3D imaging effect is better. Experimental imaging tests were conducted on different targets, and the results demonstrate that the proposed method effectively overcomes the non-uniform illumination problem in underwater turbid medium conditions, enabling high-quality three-dimensional imaging of targets in such environments.

Abstract ：
在大学物理中，光的干涉和衍射现象是描述光的粒子性和波动性非常常见的内容。那么光的干涉需满足相干条件，即两束光具有相同的偏振态、相同的频率和固定的相位差。因此，在标量衍射理论中，完全正交偏振的光不能够发生干涉现象。为拓展和探究正交偏振态下两束光相遇时光场的矢量变化，本文构建了基于马赫-曾德尔配置的正交偏振光(即正交线偏振和正交圆偏振)相干涉而产生的光场，利用检偏器检测光场的矢量特征及条纹分布情况。结果表明正交偏振光相干涉产生了周期性的矢量光场。该研究能够帮助学生更加直观的掌握波片及偏振片调制不同偏振态的光束并实现矢量光场的检测和分析。

Abstract ：
In the rapidly evolving fields of Augmented Reality (AR) and Virtual Reality (VR), achieving high diffraction efficiency and a wide field of view (FOV) is critical for enhancing visual experience. This paper presents a three-layer Polarisation Volume Grating (TL-PVG) structure designed to address the limitations of single-layer PVGs in AR/VR applications. By stacking multiple PVG layers with different tilt angles, TL-PVG achieves an expanded angular bandwidth and improved diffraction efficiency, enabling brighter and more immersive displays. The proposed TL-PVG structure incorporates polarisation multiplexing to optimise the optical diffraction efficiency by approximately 75%, thereby enhancing image brightness and sharpness. The experimental results demonstrate that TL-PVG significantly outperforms traditional single-layer PVGs, offering a promising solution for waveguide elements in next-generation AR/VR displays. This study provides a comprehensive analysis of the fabrication process, optical properties, and applications of TL-PVGs, highlighting their potential to revolutionise the AR/VR technology.

Abstract ：
Optical encryption based on interferenceless coding aperture correlation holography (I-COACH) is one of the holographic encryption technologies. I-COACH with dual-channel has been employed to encrypt two plaintexts, not only is the encryption capacity limited, but when the two plaintexts are horizontally overlapped, the crosstalk between the two decrypted plaintexts becomes significant. To address these issues, we present an optical multiple images encryption system based on single-channel I-COACH. In our optical encryption system, the multiple images are placed adjacent to each other and encrypted simultaneously through a single-shot I-COACH. The traditional cross-correlation methods fail to decrypt the multiple plaintexts, we propose a decryption scheme based on a novel deep learning framework (M-Net). The multiple plaintexts can be decrypted from a single ciphertext simultaneously, greatly improving the decryption efficiency by our method. Moreover, the crosstalk between the multiple images is avoided. Various experiments are conducted to demonstrate the effectiveness and feasibility of our proposal.

Abstract ：
With the rapid advancement of high-speed communication and computational technologies, AR and VR are regarded as next-generation platforms for immersive human-digital interaction. Polarization Volume Gratings (PVGs) is a game-changing breakthrough in the fast-growing field of augmented reality and virtual reality (AR/VR), considerably advancing holographic waveguide applications. However, replicating the sophisticated performance of human vision while keeping tiny and lightweight near-eye display modules is a huge problem for optical engineers. Recent advances in holographic optical elements (HOEs) and lithography-enabled devices are highlighted as novel approaches to overcoming classic optical restrictions in AR and VR systems. High-resolution-density and high-brightness Liquid Crystal (LC) technology is a promising picture source for see-through AR displays, particularly in bright environments. This comprehensive study investigates the emerging significance of planar and ultrathin diffractive LC polarization optical elements in AR and VR. Ultrathin planar diffractive LC optical elements, like reflective phase LC gratings, geometric phase LC grating and lens, have proven useful in AR and VR for a variety of purposes, including Exit Pupil Expansion (EPE), enlightening field of view (FOV), reducing chromatic aberrations, and achieving gaze-matched Maxwellian displays through dynamic pupil steering. This analysis concludes with a discussion of future research directions, paving the way for the next generation of advances in photonic devices for AR and VR displays.

Abstract ：
In interferenceless coded aperture correlation holography with incoherent illumination(I-COACH), point spread hologram(PSH) is important and it is usually necessary to record the PSH library priori. However, the recording of PSH library is time-consuming and basiclly difficult to obtain ideal PSH. The reconstructions correspondingly suffer from some noise which results from the cross-correlation reconstruction of nonideal PSH and object ho-logram (OH). Here a deep-learning-based interferenceless coded aperture correlation holographic imaging technique (DP-based I-COACH) is developed, in which the object can be reconstructed directly from a single-shot object hologram (OH) without any point spread hologram priori. In DP-based I-COACH, a convolutional neural network (CNN) composed of five encoders and four decoders which follows the encoder-decoder "U-net" ar-chitecture is employed. Different object intensity patterns recorded by single-shot together with their associated ground truth form data pairs, are used to train the CNN. In order to demonstrate the reliability of our proposed method, the imaging performances of our proposal is investigated under different experimental conditions, the reconstruction image quality is obviously improved compared with other reconstruction algorithms. The depth of field extension of our proposal without sacrificing the imaging quality and increasing the complexity of system is also described, which will drive the application of I-COACH in some potential scenarios, such as endoscopic application.

Abstract ：
Extending depth-of-field (DOF) of the imaging system without modifying the structure and sacrificing imaging performances of the optical system is of great significance to broaden the capability and application of the imaging system. In this paper, the interferenceless coded aperture correlation holography(I-COACH) is developed to be a large-depth incoherent imaging system by employing an annular multi-focal coded phase mask (AM-CPM). Based on the analyses of axial defocus characteristics in I-COACH, the defocus compensation function is defined, the AM-CPM is designed and multiplexed on the system optical pupil, which plays the role of a gradual lens. In AM-CPM, multi-annular zones with different focal lengths are used to compensate different axial defocus aberrations and adjacent annular zones have symmetric axial defocus aberration correction capability according to the imaging characteristics of the system. The simulations and experimental results fully demonstrate that the axial point spread function distribution of the system obtained by AM-CPM is continuous and the development method enables the extension of the DOF of the I-COACH system by only single exposure point spread hologram. This solution is expected to provide great potential in the field of microscopic imaging and other fields of that based on I-COACH system.
