摘　　要：本文介绍了3种在全光时分复用(OTDM)系统中所采用的解复用器:一是基于 Sagnac干涉仪的光纤非线性光环路镜(NOLM)解复用器,二是采用行波半导体激光放大器的非线性光环路镜(TWSLA—NOLM)解复用器,三是基于频率转换的四波混频(FWM)解复用器。解复用嚣是全光信息处理中的关键技术之一。In this paper three all-opti- cal demultiplexers are intro- duced.One is the optical fiber nonlinear optical loop mirrow (NOLM) demultiplexer based on the Sagnac interferometer.An- other NOLM demultiplexer is based on travelling wave semi- conductor laser amplifier (TWSLA).The other is four-wave mixing (FWM) demultiplexer.The demultiplexer represents one of the key technologies in all-optical signal processing.
