| 摘 要： | 基于偏振态的耦合非线性薛定谔方程,采用分步傅里叶法分析了控制光与信号光偏振失配对双耦合器非线性光纤环镜(NOLM)性能的影响.结果表明,偏振失配导致NOLM输出脉冲出现波形畸变以及时间抖动和强度波动.并且随着工作速率的提高,时间抖动和强度波动随之加剧.

| Abstract: | The impact of the polarization dismatch between control light and signal light on the nonlin- ear optical loop mirror(NOLM)with two couplers was analysed by using split-step Fourier method (SSFM)that can solve the coupled nonlinear Schr6dinger equation(CNLSE)considering the polariza- tion effect.The simulations show that the waveform distortion,the time jitter and the intensity fluc- tuation of the output signal are induced by the polarization dismatch.And the time jitter and the inten- sity fluctuation are aggravated with the increase of the working speed. |
