摘要
本文报道了几种光纤通信用偏振无关光环行器，对它们的原理做了简要介绍。尤其着重于以双折射晶体、法拉第旋转器、二分之一波片为基本元件的双光纤三端口环行器。
This paper reports a few kinds of polarization- independent optical circulator in fiber optic communication, generally introduces their principles. The important part is the double -fiber three ports circulator whose basic components are composed of birefringent crystals, two Faraday Rotators and 1/2waveplates.
