摘　　要：在理论及实验上分析了影响光环行器插入损耗及反向隔离比的因素,讨论了环行器中起、检偏镜参数对其性能的影响.结果表明,起、检偏镜的各组参数存在最佳选择,以保证环行器具有低插损、高隔离比及与偏振无关的特性.作者研制的环行器正向损耗小于1dB,反向隔离比在25.5dB与28dB之间.In this paper the factors which influence the isolation and the insertion loss of optical circulator are discussed. Theoretically and experimently ther is an optimum chioce between absorption and polarization characteristics of polarizing prism for a polarization-incependent optical circulator with low insertion loss and high isolation. Experiment shows that the insertion loss of our circulator was about-1dB and the isolation was between - 25.5dB and - 28dB.
