该文对基于非线性非对称光纤耦合器的全光逻辑门进行了研究。利用耦合器中光脉冲传输的耦合模方程，在两输入端口不同的功率组合情形下，对两输出端口输出功率进行数值计算，得到消光比，再根据消光比判定实现逻辑门功能。研究表明：信号从不同输入端口输入，非对称耦合器有不同的开关阈值。在两输入端口选择不同的输入功率组合，可实现不同的逻辑门运算。

The paper has done some research about all-optical logic gates based on nonlinear asymmetric fiber coupler .Under different power combiner of the input ports , do numerical calculation of the output ports power with the coupled-mode equations , and get the extinction ratio .According to the extinction ratio , then decide the different logic gates .The studies show that the signal input from different port , and the asymmetric coupler has different switching threshold .We choose different combination of input power in the two input ports , we can achieve different logic gate operator .
