摘要
采用腔量子电动力学 (QED)方法 ,定量讨论了平面结构微腔半导体激光器的自发发射特征物理量随腔结构的变化规律 .在微腔半导体激光器自发发射因子调制、自发发射寿命调制以及一些实验依据的基础上 ,提出了微腔结构调制方法 .数值模拟了其脉码在光纤中的传输图形 .结果表明 。
The cavity quantum electrodynamics (QED) method is adopted to discuss quantitatively the variation of spontaneous emission characteristic quantities versus the cavity structures in planar microcavity semiconductor lasers.Basing on the spontaneous emission factor modulation and spontaneous emission lifetime modulation and some experiments on microcavity semiconductor laser,a method on microcavity structure modulation is proposed.Its pulses transmission in fibres are simulated numerically.The results show that this modulation has an advantage over the current modulation in pulse bit rate.
