    Design and Analysis of a Microstructure Ring Fiber for Orbital Angular Momentum Transmission

    Design and Analysis of a Microstructure Ring Fiber for Orbital Angular Momentum Transmission by Gai Zhou, Guiyao Zhou, Cheng Chen, MinNan Xu, Changming Xia, Zhiyun Hou

    Published 2016-01-01

    In this paper, we propose a novel microstructure fiber with annular core for transmitting optical orbital angular momentum (OAM), and the OAM modes are calculated under different structure parameters of the fiber. Compared with the previous hollow step-index ring fiber, the proposed fiber brings hig...

    Hybrid Coding and Filtering Technique for Optical IM-DD Link With Robustness to Multipath Interference and Bandwidth Limitation

    Hybrid Coding and Filtering Technique for Optical IM-DD Link With Robustness to Multipath Interference and Bandwidth Limitation by Lin Sun, Gai Zhou, Qirui Fan, Alan Pak Tao Lau, Changjian Guo, Chao Lu

    Published 2021-01-01

    In this work, a hybrid code division multiplexing (CDM) coding and digital filtering method for optical intensity modulation and direct detection (IM-DD) link is investigated to address multipath interference (MPI) and channel bandwidth limitation. CDM signaling already provides robustness to MPI th...

    Tailoring the Generalized 2D Airy Beam

    Tailoring the Generalized 2D Airy Beam by Junpeng Zheng, Ruhao Zhao, Cong Zhang, Meng Xiang, Gai Zhou, Yi Xu, Songnian Fu, Yuwen Qin

    Published 2024-01-01

    Generalized two-dimensional (2D) Airy beam is a kind of self-accelerating beam with variable initial angle between its two wings, manifested itself as an initial angle determined parabolic trajectory during the free-space propagation. However, the independent and flexible manipulation of both the tr...

    Superpixel Technique Enabled Spatial Phase Modulation Equalization for Power-Efficient Vortex Beam Generation

    Superpixel Technique Enabled Spatial Phase Modulation Equalization for Power-Efficient Vortex Beam Generation by Ruhao Zhao, Junpeng Zheng, Cong Zhang, Meng Xiang, Gai Zhou, Yi Xu, Yuwen Qin, Songnian Fu

    Published 2024-01-01

    Realizing a spatial phase modulation (SPM) from 0 to 2π is vital for achieving precise light field manipulation, when the phase-only spatial light modulator (SLM) is driven by the voltage. However, insufficient bias voltage degrades the quality of the generated structured light. Here, we...
