| 摘 要： | 星间相干光通信系统中,信号光与本振光的不同分布将影响外差混频效率.在假设信号光与本振光偏振一致、相位匹配、几何中心重合的前提下,详细推导了信号光振幅为平面波(Uniform)、高斯(Gauss)分布,本振光为艾里斑(Airy)、Uniform及Gauss分布时的6种外差混频效率关系式,其中4种得到了精确的解析式.在此基...

| Abstract: | The difference of amplitude profile between signal and local oscillator wave will affect the heterodyne efficiency of the inter-satellite coherent optical communication system.Based on the assumption that signal and local oscillator wave have the same polarization and geometric center,and that they are phase matching,the detailed derivation of heterodyne efficiency is given when the signal has uniform or Gauss distributions,and the local oscillator wave has Airy,uniform or Gaussan distributions.The accurate... |
