Paper Abstract

The recent development of vertical-cavity surface-emitting lasers or whispering-gallery mode microdisk lasers opens the possibility of altering the photon density of states and the spontaneous carrier lifetime of the active medium. In this paper we investigate the corresponding changes of the stationary and dynamical emission properties of these microcavity lasers. We present a quantum mechanical theory for the coupled photon- carrier system in a semiconductor microcavity which includes the relevant nonequilibrium and many-body effects in the carrier system and mode confinement effects in the photon system. The theory considers the spectral interplay of stimulated and spontaneous emission and the cavity loss according to a kinetic equation for the spectral laser intensity. The nonequilibrium dynamics of the carrier system is discussed in terms of a Boltzmann equation which includes carrier-photon, carrier-carrier and carrier-phonon scattering.
