摘　　要：在环形器设计中引入双尾纤和透镜对,使光环形器中器件功能复用,成功设计了一种具有功能复用的新型双通道多功能光环行器。利用琼斯矩阵对其进行了传输特性理论分析。分析表明,该器件具有与单尾纤光环行器相同的低插入损耗(IL)、零偏振模式色散(PMD)和高隔离度(IS)等特性。Using two-fiber tips and lens twice, we have advanced an innovated double-channel optical circulator, which duplicate the function in comparison with conventional optical circulator with single fiber tip. Typical polarization mode dispersion (PMD), insertion loss (IL) and isolation (IS) of the developed circulator are as good as conventional optical circulator's characteristics in theory. It's most important that the circulators, which can be fabricated with duplicated function and high characteristics, also have a low cost and a small volume comparatively.
