Numerical analysis of steady state characteristics of InGaAsP/InP-BC lasers

本文通过采用有限差分法对描述缓变波导半导体激光器稳态特性方程组的数值分析,对InGaAsP/InP掩埋新月形激光器的阈值、波导、侧向模式进行了理论求解。结果表明,它具有良好的基横模工作特性和稳定的光场分布,与实验相符。

Theoretical analysis for the threshold, waveguide and lateral mode characteristics of InGaAsP/InP BC lasers is made by a numerical solution of the equations describing the steady state characteristics of graded waveguide semiconductor lasers. The calculating results show that a good fundamental transverse mode characteristics and stable optical field distribution can be easily obtained with BC lasers, which is in agreement with experimental results.
