摘要
提出了 NOLM中反向信号脉冲与控制脉冲耦合方程 ,研究了正、反向信号脉冲在传输过程中共同作用的非线性相移 ,分析了高斯脉冲和 NRZ码在此情况下的开关特性 ,得到了有反向交叉相位调制时的第一最佳解复用长度。
Coupling equation between counter propagating signal and control pulse in nonlinear optical loop mirror (NOLM) is proposed.Nonlinear phase shift deference between the co propagating and the counter propagating signal in transmission process is studied.And the switching characteristics of Gaussian and non return zero (NRZ) pulse is analyzed.The first best de multiplexing lengths,switching windows,output waveform and so on,which are important in practical usage,have been gotten.
