本文报导一种新型偏振无关光环行器的设计及实验结果。器件由偏振分离器、偏振组合器、法拉弟旋转器及半波片组成。对1.37微米不同偏振方向入射光,器件的插入损耗为2.8分贝,隔离为18～35分贝。

The design and experimental results of a new polarization-independent optical circulator are reported. It consists of a polarizing splitter, a polarizing combiner, a Faraday rotator and a half-wave plate. Insertion losses of 2.8 db and isolation of 18-35 db were obtained for different polarization directions of incident light at 1.37μ/m.
