摘要
提出了反向交叉相位调制 (XPM)耦合方程 ,得出了非线性光学环路镜 (NOLM)中正、反向信号脉冲在传输过程中共同作用的非线性相移 ,研究了高斯脉冲情况下NOLM的开关特性 ,NOLM作为解复用器时反向XPM的影响 ,及作为光路由选择单元时无放大联接的级数 .最后讨论NRZ码情况下的开关特性 .
Coupling equation of counter cross phase modulation (XPM) is proposed.In nonlinear optical loop mirror (NOLM),nonlinear phase shift difference between the co propagating and the counter propagating signal in transmission process is gotten.The switching characteristics on Gaussian pulse,the effect of XPM on de multiplexer which adopts NOLM and the progression without amplifier in an experiment adopting NOLM in all optical routing are analyzed.In the end,we discuss the switching characteristics on non return zero (NRZ) codes.
