半导体激光器动态频率飘移的大信号分析

DYNAMIC FREQUENCY SHIFT OF LATGE SIGNAL MODUIATIONIN A SEMICONDUCTOR LASER

本文研究了半导体激光器(LD)在大信号下的动态频率飘移(DFS),分析表明:提高LD的偏置电流,增大调制电流的幅度可以抑制DFS。

This paper researches Dyanmic frequency shift (DFS) of semiconductor lasers (LD). The analysis points out; DFS can be suppresed by increasing bias current and magnitued of modulating current of LD
