摘要

研究了6倍叠短腔量子点(QD)激光器在/spl mu/sec时间范围内的时间分辨纵向模式动力学。测量分别在室温和100K下进行。开启单个纵向模态的红移后，同时观测到模群的蓝移和光谱平均值的红移。计算了由于衬底漏模引起的温度依赖性泄漏损耗谱。理论预测的模群蓝移与实验数据吻合较好。

Spectral mode dynamics of short cavity quantum-dot lasers at 1.13 /spl mu/m

Temporally resolved longitudinal mode dynamics for 6-fold stacked short cavity quantum dot (QD) lasers is investigated in the /spl mu/sec time-range. Measurements were performed at room temperature and at 100K. After turn-on a red-shift of single longitudinal modes, a blue-shift of the mode groups and a red shift of the mean value of the spectra are observed simultaneously. Temperature dependent leakage loss spectra due to leaky substrate modes are calculated. The blue shift of the mode-grouping, predicted by the theory, is in good agreement with the experimental data.
