摘要

研究了一种新型半导体激光器——双非对称势垒层量子点激光器的静态和动态特性。考虑了量子点中载流子进入激光基态的直接和间接捕获。在间接捕获的情况下，载流子的点内弛豫控制着激光特性，而在直接捕获和间接捕获的情况下，载流子的点内弛豫不是一个重要的因素。在后一种情况下，输出光功率和调制带宽都大大增加。

Lasers with double asymmetric barrier layers: Direct versus indirect capture of carriers into the lasing ground state in quantum dots

Static and dynamic characteristics of a quantum dot (QD) laser with double asymmetric barrier layers – an advanced type of semiconductor laser – are studied. Both direct and indirect capture of carriers into the lasing ground state in QDs is considered. The intradot relaxation of carriers, which controls the laser characteristics in the case of only indirect capture, is shown to not be a significant factor in the case of both direct and indirect capture. In the latter case, both the output optical power and modulation bandwidth are considerably increased.
