    Control Bandwidth Promotion of Adaptive Fiber-Optics Collimator and Its Application in Coherent Beam Combination

    Control Bandwidth Promotion of Adaptive Fiber-Optics Collimator and Its Application in Coherent Beam Combination by Guan Huang, Chao Geng, Feng Li, Jiaying Liu, Xinyang Li

    Published 2018-01-01

    Adaptive fiber-optics collimator (AFOC) plays an important role in the coherent beam combining (CBC) systems. To improve the control bandwidth, the frequency characteristics of AFOC are measured, and an accurate transfer function model is established. Through the analysis of this model, we find that...

    Adaptive SMF Coupling Based on Precise-Delayed SPGD Algorithm and Its Application in Free Space Optical Communication

    Adaptive SMF Coupling Based on Precise-Delayed SPGD Algorithm and Its Application in Free Space Optical Communication by Guan Huang, Chao Geng, Feng Li, Yan Yang, Xinyang Li

    Published 2018-01-01

    The adaptive coupling of laser beam from space into single-mode fiber (SMF) plays an important role in the fiber-based free space optical communication technology. This paper investigates a kind of adaptive SMF coupling system based on a novel corrector named adaptive fiber coupler, and an improved...
