摘　　要：为了满足建设低功耗、轻小型空间激光通信网络的需求,提出了基于逆向调制原理的光空分多址式无线激光通信组网方案。应用ZEMAX软件设计像方远心镜头,实现收发光束的逆向通信。通过离焦方法进行光斑扩展,提升空间光-光纤阵列的耦合效率,并用MATLAB软件进行仿真。结果表明:对于纤芯/包层/涂覆层直径为105μm/125μm/250μm的正六边形排列的光纤阵列,光斑半径从40μm增加到80μm,有效视场覆盖率提升25.6%,系统工作稳定性提升50%,光斑扩展有利于空间光-光纤阵列耦合的连续性和稳定性。In order to meet the needs of building a low-power, light and small space laser communication network, an optical space division multiple access wireless laser communication networking scheme based on the principle of inverse modulation is proposed. ZEMAX software is used to design the image-space telecentric lens to realize the reverse communication of receiving and sending beams. The defocus method is used to expand the facular to improve the coupling efficiency of the space laser-fiber array, and the simulation is carried out with MATLAB software. The results show that: for a regular hexagonal fiber array with a core/cladding/coating diameter of 105 μm/125 μm/250 μm, the facular radius is increased from 40 μm to 80 μm, the effective field of view coverage is increased by 25.6%, and the system stability increased by 50%. The facular expansion is conducive to the continuity and stability of the space laser-fiber array coupling.
