【摘要】 本文对两种微腔结构的半导体激光器进行了理论分析。对平面微腔结构，详细研究了自发发射特征物理量与微腔结构的定量关系，在微腔半导体激光器自发发射因子调制和自发发射寿命调制以及一些实验依据的基础上，提出微腔结构调制方法，讨论了微腔半导体激光器的脉码输出特性，数值模拟了其脉码在不同参数下光纤传输图形，结果表明，微腔结构调制方法在带宽等特性上优于同参数下的其它调制方法；对具有氧化孔径层的圆柱形微腔结构，分析了能解决衍射特性的理论模型并对后续工作进行了探讨。更多还原

【Abstract】 Microcavity semiconductor lasers with two kinds of structures are analyzied theoretically in this paper.For plane microcavity structures with one-dimensional distributed Bragg reflector (DBR), on the basis of the spontaneous emission modulation, the spontaneous lifetime modulation and some experiments on microcavity, microcavity structure modulation, a new modulation method, is present, and the corresponding pulse codes output characteristics of microcavity semiconductor lasers are discussed. Meanwhile, the propagation of pulse codes in optical fibers under various parameters is simulated numerically. The results show that microcavity structure modulation is superior to other modulation methods in bandwidth and so on.For oxide-confined vertical-cavity surface-emitting lasers (VCSEL?s), vectorial model based on Maxwell equations is developed, which gives the basic theory for a further research.更多还原
