摘要
利用金属镜面微腔激光器中真空场和量子阱中电子态函数,对比了TE模和TM模的自发发射谱.发现腔长为半个波长的微腔激光器可以增进TE模垂直方向的自发发射,同时TM模却得到很大抑制,并且它们总的自发发射也存在差异.
Based on the vacuum field in a micro cavity laser with metallic mirrors and the state of electron in a quantum well,the TE mode and TM mode spontaneous emission spectra are compared.The results show that the TE mode spontaneous emission in the direction perpendicular to the surface can be enhanced when the length of the microcavity is the half of the wavelength,while the TM mode spontaneous emission is suppressed.There is also difference between their total spontaneous emission.
