Theory of photoluminescence of microcavity exciton-polaritons in the strong coupling regime

Summary form only given. Quarter wavelength stacks of transparent semiconductors, known as Bragg reflectors (DBR), are used to efficiently confine the light in recently realized semiconductor microcavities. The resulting cavity mode may then be coupled to an exciton resonance by inserting a quantum well (QW) inside the cavity. It is well known that the photoluminescence dynamics in these structures is determined by the combined energy relaxation produced by phonon emission and radiative recombination. We have calculated both scattering rates of microcavity exciton-polaritons with acoustic phonons and radiative recombination rates of a realistic microcavity in the strong coupling regime and used them to simulate the photoluminescence dynamics.
