| 摘 要： | 本文以激光器单模速率方程为基础，针对ＤＦＢ－ＬＤ推导了光子寿命与激光器内部损耗及端面出射损耗的关系，以及端面出射光功率与平均光子密度的关系，给出吸收光栅增益耦合ＤＦＢＬＤ电路模型，用该模型研究了ＡＧ－ＧＣ－ＤＦＢ－ＬＤ的自脉动效应及影响自脉动幅度和频率的主要因素。

| Abstract: | A circuit model for absorption grating (AG) gain coupled (GC) distributed feedback (DFB) semiconductor laser diodes (LD) is presented,based on the rate equations of carrier densities in active region and absorption grating,as well as the photon density.The relation of photon lifetime to cavity loss and facet loss,and the relation of light power to average photon density are derived.As an example,the self pulsation in AG GC DFB LD is studied. |
