摘　　要： 基于考虑时间失配的耦合非线性薛定谔方程,采用分步傅里叶法分析了双耦合器非线性光纤环镜(NOLM)中控制光与信号光的时间失配对NOLM性能的影响.研究结果表明,时间失配引起输出脉冲波形畸变、产生脉座、造成一定的强度波动,并且引起输出脉冲时间抖动,脉冲的码率越高,时间抖动也随之急剧增大. The impact of time dismatch between control light and signal light on NOLM with two couplers was studied by the split-step Fourier method （SSFM）, which is effective to solve the coupled nonlinear Schrodinger equation （CNLSE）. It is obtained by simulation that time jitter and intensity fluctuation of the output signal are induced by the time dismatch. The output waveform is distorted and the pedestal is produced. The time jitter is aggravated with the increase of signal bit-rate.
