本文分析选频滤波器负载外腔半导体激光器的调谐特性。从等效模型的受激条件出发,导出确定最大调谐范围的简单表达式,提出了计算在各种反馈强度下调谐曲线的方法,并解释近年来报道的有关实验结果。

This paper presents a theoretical study of the tunability of frequency selective filter extended cavity semiconductor lasers. From the lasing condition of the equivalent model, we derive a simple expression determining the maximum tuning range and propose a computing method for calculating the tuning curve at any feedback level. We also explain several experimental observations reported recently.
