Investigations of quantum effects in semiconductor quantum-well microcavities interacting with laser light in the strong-coupling regime are presented. Modifications of quantum fluctuations of the outgoing light are expected due to the non-linearity originating from coherent exciton-exciton scatteri

Abstract
We report the observation of optical bistability in a semiconductor microcavity pumped at the βmagic angleβ above the parametric oscillation threshold. Experimental evidence is given in the form of a hysteresis cycle of the nonlinear emission as a function of the pump intensity. A model analogous to those developped for triply resonant Optical Parametric Oscillators (OPO) is in good agreement with the experimental findings. In the second part, we study the potential application of the parametric oscillation regime to quantum optics. The quantum correlations between the emitted βsignalβ and βidlerβ beams are computed. We show that very strong quantum correlations between the signal and idler polaritons can be achieved. However the quantum effects in the outgoing light fields are strongly reduced due to the large mismatch in the coupling of the signal and idler polaritons to the external photons.

Recent theoretical results are presented for the non-linear dynamics of resonantly excited semiconductor microcavities in the strong exciton-photon coupling regime. Treating the microcavity polaritons as a system of interacting bosons, the model describes the very efficient polariton parametric ampl
## Abstract Polarisation properties of the light emitted by a semiconductor microcavity are studied in the regime of stimulated parametric scattering for one and two beam continuous wave excitation. For linearly polarized excitation with one beam we observe strongly linearly polarized signal emissi
