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 3dBm, the continuous probe power of 0dBm and the bias current of 600mA, under which best XOR output performance with the extinction ratio(ER) of about 11.5dB, 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.
