摘要
从麦克斯维方程组出发 ,推导得出了双外腔半导体激光器在任意量双外部反馈情况下的速率方程 利用数值分析方法 ,研究了双外腔反射半导体激光器的动态特征 研究发现 :当激光器注入电流高于阈值时 ,双外腔反射会引起激光器输出的低频波动现象 并研究了低频波动的频率与反馈量的关系 。
The dynamics of the semiconductor laser with two optical feedbacks was studied. A new set of nonlinear rate equations that can describe the external cavity semiconductor laser with any amount of two optical feedbacks are proposed. It was found that when laser was biased above the threshold and operates in regime V, another feedback can induce low frequency fluctuations.
