摘要
本文介绍梭镜分光式光学环行器设计理论与制备工艺以及在光纤通信和光纤传感系统中的应用．所研制的光学环行器光纤－光纤（单模）插入损耗小于２．８ｄＢ，隔离比大于２５ｄＢ，回波损耗优于４０ｄＢ。器件性能与偏振无关。
The design theory and fabrication technique of the optical circulator with pris-matic polarizing beam splitter and its applications in the fibre communication and sensingsystems are presented in this ljaper The parameters of the optical circulator fabricatedhave been measured with an insertion loss less than 2.8dB,isolation ratio greater than 25dBand echo-wave loss greater than 40dB, The characteristics of the device are insensitive tothe polarication of the input light
