谱线展宽因子是半导体激光器的重要参数之一 .本文在分析了半导体激光器有源区折射率和增益对载流子的依赖关系的基础上 ,给出了展宽因子α的定义式 .实验测得 1 .3μmInGaAsP半导体激光器的α因子的值约为 3.96 .
Spectral broadening factor is one of the most important parameters of semiconductor lasers.This paper gives the definition of broadening factor α on the basis of analyzing the dependence of the refractive index and gain on the carrier in the active region of the semiconductor laser.Experimental results The 1.3 factor InGaAsP semiconductor laser has an alpha factor of about 3.96.
