半导体激光器光电混合双稳装置的双稳特性与器件参量之间的关系

Dependence of the characteristics on the parameters of a hybrid electro-optic bistable devce of semiconductor laser

报导了输出反馈泵浦型双稳半导体激光器双稳特性随器体参量变化的实验结果。双稳实验曲线和理论计算曲线的对比分析表明，双稳特性随各参量变化的规律完全相同。实验和理论之间的微小差别来源于光探测器的实测饱和曲线和理论模型之间的差异，以及实际的半导体激光器存在自发辐射。

Dependence of the characteristics of the bistable semiconductor laser by output-feedback pumpingscheme on the parameters of the device has been experimentally observed and reported. By contrasting the mea-sured bistability with the theoretical calculation curves,it was found that the experimental and the theoretical pat-terns of the bistability are almost the same when the device parameters are changed.There are little differences be-tween the two curves because the practical saturation curves of the photodetector deviate from the theoretical mod-el,and the spontaneous emission is ignored in the theory.
