摘　　要：本文针对增益透明半导体光放大器(GT-SOA)的偏振旋转效应进行了研究,并将其利用于光纤环型全光缓存器中作为偏振旋转光开关,作为全光缓存器的关键器件。本文根据增益透明半导体光放大器(GT-SOA)的偏振旋转效应理论模型编制仿真软件。建立了基于GT-SOA偏振旋转效应的全光缓存器仿真系统,将GT-SOA的仿真模块嵌入系统仿真软件中进行仿真,并对其单波长缓存系统中信号速率、传输码型、缓存时间等对系统性能的影响进行了仿真和分析。仿真分析结果表明,在该缓存系统中GT-SOA可以很好的完成光开关的作用。l In this paper studied the polarization ratation in gain transparent SOA, and set up a polarization rotation optical switch used gain-transparent semiconductor optical amplifier based on XPM effect. The GT-SOA is the key device of the buffer system. This paper worked out the simulation software on the basis of the theoretical model of GT-SOA. Then established the all-optical buffer system based on GT-SOA, and embedded GT-SOA simulation module in the system simulation software. This paper studied the effect of signal rate, transmission code, buffer time in the single wavelength system. Study shows GT-SOA acted as an effective switch in the all-optical buffer system.
