摘　　要：为了实现全光逻辑的仿真运算,基于Simulink模块可视化的特点,根据线性光放大器交叉增益调制原理的理论模型,采用模块搭建的方法,实现了全光逻辑"或非"的运算。结果表明,通过Simulink的模块搭建,使其更好地仿真出逻辑"或非"输出结果;适当地选择注入电流组合,逻辑或非的运算效果越佳;由于模块化的结构容易进行修改和扩充,通过模块搭建用于更多的逻辑运算也是可行的。In order to simulate all-optical logic operation, based on visualization characteristics of the Simulink module, according to the theory of cross-gain modulation （ XGM ） of linear optical amplifiers （ LOA ）, the logic NOR gate operation was achieved by means of modular building method. Results show that the Simulink module can be used to simulate better output results; Proper input eurrent groups have the advantages to achieve better logic operation effect. Because the modular structure can be modified and expanded easily, modular building can be used in more logical operations too.
