Abstract

Recently an unusual behaviour of the polariton-polariton scattering in a semiconductor microcavity (MC) under a strong continuous resonant excitation near the lower polariton branch has been observed (Kulakovskii et al 2001 Nanotechnology 12 475). The maxima of the scattered photoluminescence signal above the threshold of parametric scattering does not shift along the microcavity lower polariton branch with change of the pump detuning or angle of incidence but is always directed approximately perpendicular to the MC plane. We discuss theoretically a possible explanation of such behaviour via a competition between two instabilities in the polariton-polariton scattering, stimulated polariton-polariton scattering and bistability of the pumped polariton mode response.
