摘　　要：分析有SOA辅助设计的Sagnac全光逻辑异或门、SOA-MZI全光逻辑异或门和基于SOA-MZI双端输入的全光逻辑异或门的结构及工作原理,比较3种逻辑异或门的性能、系统的复杂度等.在此基础上,提出一种改进的基于SOA-MZI全光逻辑异或门,并分析方案的可行性.最后讨论方案的数学模型及建模方案.数值分析表明,该方案能够有效的实现逻辑异或功能,且适当调整参数,系统性能将优于现有的SOA-MZI全光逻辑异或门.The structures and working operations of SOA-assisted Sagnac XOR gate, all-optical MZI XOR gate and the SOA-assisted bidirectional data input and the complexity of the system were compared. XCIR gate were analyzed; then the mree AUK S perlormance Based on it, a modified SOA-MZI-based all-optical XOR logic gate was proposed. The feasibility of the program was analyzed. Finally, the optical principle and mathematical model of the program were discussed. Values analysis shows that the program can effectively achieve the XOR function, and appropriately adjust the parameters, the system performance will be superior to the existing XOR gate.
