微加工获得的F-P半导体激光器的光谱特性分析

Analysis of output spectrum of micromachined FabryPerot semiconductor lasers

摘要: 利用微加工法可以在FP半导体激光器中引入具有反射功能的缺欠点或面来改进激光器的光谱特性。作者导出了含有多个缺欠点的微加工获得的FP半导体激光器(MMLD)的输出谱表达式,并对MMLD振荡模的边模被抑制的情况作了简要的说明。

Abstract: Micromachined defects can be introduced into a semiconductor laser to improve spectral characteristics of the F-P laser. In this paper,the analytical expression of the output spectrum from the micromachined F-P diode laser (MMLD) has been deduced. Moreover,a brief account has been given to explain the side mode suppression of the MMLDs.
