我们对单片多段锁模 DBR 激光器的定时抖动进行了理论分析，结果与实验测量结果吻合良好。该分析使用具有 Langevin 自发发射噪声的行波方程模型，并包括增益非线性、自相位调制和 DBR 滤波的重要物理效应。研究发现自发噪声限制了低抖动操作。研究了频率失谐对定时抖动的影响，并讨论了激光参数（例如线宽增强因子和增益段长度）对实现低抖动脉冲的影响。
We present a theoretical analysis of the timing jitter in monolithic multisection mode-locked DBR lasers which is shown to agree well with experimental measurements. The analysis uses a traveling-wave equation model with Langevin spontaneous emission noise and includes the important physical effects of gain nonlinearities, self-phase modulation, and the presence of DBR filtering. It is found that spontaneous noise limits low-jitter operation. The impact of frequency detuning on the timing jitter is studied and the effects of laser parameters, such as linewidth enhancement factor and gain section length, are discussed for achieving low-jitter pulses.
