| Abstract: | 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. |
