摘要

建立了分离触点锥形激光器的仿真模型。利用该模型模拟了脊波导和锥段分离注入的980 nm In-Ga-As器件。定性分析结果与实验结果吻合较好。讨论了脊波导部分强抽运所观察到的光束质量改善的物理根源。

Simulation of Tapered Lasers with Separate Contacts

A simulation model for tapered lasers with separated contacts has been developed. The model has been used to simulate 980 nm In-Ga-As devices with separated injection of the ridge-waveguide and taper sections. A good qualitative agreement with experimental results has been obtained. The physical origin of the observed improvements in the beam quality by stronger pumping of the ridge waveguide section is discussed.
