摘要
本文从时域和频域模拟分析了单量子阱半导体激光器的温度特性 ,给出了建模方案以及各种模拟分析。结果表明它具有较好的温度特性和较大调制带宽。当温度从 2 5 0 K变化至 35 0 K时 ,调制带宽仅从 2 5 .0 0 GHz减至 2 1.72
We analyze and simulate the temperature effect on electro-optical behavior of single quantum well laser diodes (SQW-LD) both in time and frequency domains. Modeling of SQW-LD based on three-level rate equations by means of Matlab Simulink is given and various simulation methods are presented. The results show that the SQW-LD has good temperature property and wide modulation band-width. When the temperature increases from 350 K to 350 K, the modulation bandwidth decreases only from 25.00 GHz to 21.72 GHz.
