摘　　要：理论分析了SOA动态模型和SOA-MZI全光异或原理,采用光通信系统设计软件OptiSystem搭建了基于SOA-MZI的全光异或实验模型,仿真研究了注入SOA的数据信号光功率、连续探测光功率、偏置电流等工作条件对异或输出消光比、Q值以及误码性能的影响,取得了一组最佳工作条件,即数据信号光功率为3dBm,连续探测光功率为0dBm,偏置电流为600mA,此时可以得到最佳的异或输出性能:消光比约11.5dB,Q值约22,误码率约10-108量级。研究方法和相关结论可以推广到基于SOA的其他全光信号处理应用中,为未来全光网络的全面建设做准备。The SOA dynamic model and SOA-MZI all-optical XOR principles were analyzed theoretically, and the experiment model based on SOA-MZI structure was built by using software OptiSystem. Then the impacts of data signal power, continuous probe power and bias current injected into SOA on the output extinction ratio, Q factor and bit error performance were simulated and researched. Finally, a group of best working conditions were obtained as the data signal power of 3 dBm, the continuous probe power of 0 dBm and the bias current of 600 mA, under which best XOR output performance with the extinction ratio（ER） of about 11.5 dB, Q factor of about 22, and bit error rate （BER） of about 10-108 can be obtained. The methods and conclusions can be used in other all-optical signal processing applications based on SOA, to make preparation for the comprehensive construction of all-optical network in the future.
