Abstract

A systematic study of a series of InGaAs/GaAs lasers in the 1–1.3 μm optical range based on quantum wells (2D), quantum dots (0D), and quantum well-dots of transitional (0D/2D) dimensionality is presented. In a wide range of pump currents, the dependences of the lasing wavelength on the layer gain constant, a parameter which allows comparing lasers with different types of active region and various waveguide designs, are measured and analyzed. It is shown that the maximum optical gain of the quantum well-dots is significantly higher, and the range of lasing rawavelengths achievable in edge-emitting lasers without external resonators is wider than in lasers based on quantum wells and quantum dots.

基于量子阱、点和阱点的激光器中波长与增益之间的关系

摘要对一系列基于量子阱（2D）、量子点（0D）和过渡（0D/2D）维度的量子阱点的 InGaAs/GaAs 激光器进行了系统研究。在很宽的泵浦电流范围内，测量并分析了激光波长与层增益常数的关系，该参数可用于比较具有不同类型有源区和不同波导设计的激光器。结果表明，量子阱点的最大光学增益明显更高，而且与基于量子阱和量子点的激光器相比，无外部谐振器的边缘发射激光器可达到的激光波长范围更宽。
