By using microcavity physics and quantum well physics, the spontaneous emission spectra and spontaneous emission lifetime of quantum well vertical-cavity surface-emitting lasers are calculated. By studying the transfer function of the semiconductor lasers, it is found that the shortened spontaneous emission lifetime is achieved by vertical-cavity surface-emitting lasers The main reason for the response.
