调幅光注入下半导体激光器光强调制特性的实验研究
Intensity Modulation Characteristics of Optically-injected Laser Diode
半导体激光器 光强调制 增益调制 模式选择 laser diode intensity modulation gain modulation longitudinal mode competition
摘要
在受注入光调制的半导体激光器(LD)光强调制实验中,当LD的偏置电流置于某些值时,观察到其输出光强不随注入光强改变的实验现象.实验还观察到输出光强的幅度随偏置电流的增加而呈周期性变化.理论分析表明这是由于激活区内载流子消耗、带间载流子吸收综合作用的结果,而这些效应与腔内的模式选择、注入电流产生的热效应等过程有关.
Abstract
A new phenomenon that the output of a laser diode does not change with the injected light intensity which is modulated when its injection current is certain values has been found. The amplitude of output change of the laser diode varies periodically with the increase of the injection current. It is made clear through the theoretic analysis that this phenomenon is caused by stimulated emission and interband carrier absorption that depend on the longitudinal mode competition, thermal effects, and so on.
