摘　　要：利用半导体光放大器(SOA)的交叉增益调制(XGM)效应实现全光异或门,提出全光序列密码加解密方案。采用OptiSystem 7.0软件搭建基于SOA-XGM全光加解密系统,实现了10Gbps速率全光加解密运算,解密信号质量较好。实验表明,基于SOA-XGM全光加解密系统整体性能良好。Optical stream cipher encryption and decryption system is successfully demonstrated by using cross- gain modulation （XGM） technology of semiconductor optical amplifiers （ SOA ） all - optical XOR logic gates. Experimental verification of the structure is performed with OptiSystem 7.0 software. operation speed of 10Gbps data encryption and decryption operations are successfully obtained. The original plaintext signal after encryption and decryption processing still maintains better signal quality. Finally, it shows that the performance of the entire system is better.
