摘要
应用腔量子电动力学和量子阱物理 ,计算了量子阱 DBR微腔激光器的自发发射谱 .发现由于 DBR微腔和量子阱分别对光子和载流子的限制 ,单方向的自发发射可以增进约三个量级 ,总的自发发射增强一个量级 .
Based on cavity quantum electrodynamics and physics of quantum well, the spontaneous emission spectra in quantum well micro cavity lasers with DBRs have been calculated. As a result, spontaneous emission intensity in one direction can be enhanced to about10\+3 times greater than that in the semiconductor bulk material due to the confinement of the micro cavity with DBRs and quantum well to the photons and carries, respectively. The total spontaneous emission intensity also increases 10 times.
