摘要:

采用耦合系数为高斯分布的四分之一波移分布反馈半导体激光器(GDCC)的时域行波模型,对动态大信号分析进行了数值研究。结果表明,这种新型光源可以显著改善大耦合系数四分之一波移分布反馈激光器的单模特性和更多的烧孔效应修正。

英文摘要:

A numerical investigation on the dynamic large-signal analysis using a time-domain traveling wave model of quarter wave-shifted distributed feedback semiconductor lasers diode with a Gaussian distribution of the coupling coefficient (GDCC) is presented. It is found that the single-mode behavior and the more hole-burning effect corrections of quarter wave-shifted distributed feedback laser with large coupling coefficient can be improved significantly by this new proposed light source.
