摘要
本文提出微腔半导体激光器的两种新调制方法：自发发射寿命调制和光子寿命调制．小信号近似分析的数值模拟结果表明。
In this paper,new modulation methods of micro cavity semiconductor lasers,the spontaneous lifetime modulation and the photon lifetime modulation are proposed,their normalized intensity modulation responses versus the modulation frequency are obtained by analyzing rate equations of micro cavity semiconductor lasers in the condition of the small signal approximation.The numerical simulation results show that their modulation bandwidths are broader than current modulation′s;the coupling efficiency of spontaneous emission into a lasing mode,injection current and so on have influence on modulation bandwidths of the spontaneous lifetime modulation and the photon lifetime modulation;the photon lifetime modulation is superior to the spontaneous lifetime modulation in noise suppression.
