Microcavity Structure Modulation of Semiconductor Lasers and Its Pulses Transmisson in Fibre
半导体激光器的微腔结构调制及其脉码在光纤中的传输

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.
