摘　　要：全光逻辑门是实现高速光分组交换、全光地址识别、数据编码、奇偶校验、信号再生、光计算和未来高速大容量全光信号处理的关键器件,本文介绍了几种基于半导体光放大器非线性效应的全光逻辑门,分析了它们的系统结构和工作原理,并对各自的特点进行了比较,展望了光逻辑门在未来的发展方向。Optical logical gate is an kind of important device using for high-performance optical information processing and all optical networks, some example applications including high-speed optical packet-switched routers, header recognization, parity checking and data encode and so on.Several kinds of optical logical gates based on nolinear optical effection is introduced too, its structure as well as principle is analysised and discussed. In conclusion, optical logical gates is popular in future.
