Etude théorique des propriétés non-classiques de la lumière émise par des microcavités semiconductrices dans le
régime de couplage fort

Abstract : This manuscript is a theoretical study of the non-classical properties of the light emitted by the semiconductor microcavities in the strong coupling regime. In this respect, we have studied both single photon and twin photon sources based on polariton-polariton interactions. In a first part, we have demonstrated the possible realization of a sub-poissonian light source based on photon confined structures. For a small enough photonic dot embedded in a planar microcavity, one can reach a non-linear regime where the introduction of one single photon is sufficient to detune the resonance by more than a linewidth. This leads to the so-called polariton quantum blockade. In this regime, we have shown that it is possible to create a novel single photon source, presenting in detail its intrinsic properties. We have highlighted the various aspects of its performance, in the continous regime as well as in the pulsed regime. In the second part, we have studied the quantum correlations properties of ring-shaped parametric fluorescence from a planar microcavity excited by a symmetric two-pump excitation. Using a Wigner Quantum Monte Carlo algorithm, we have characterized the quantum correlations taking place between the signal and idler beams on the opposite sides of the ring. The results indicate that even in presence of multiple scattering, realistic losses and static disorder, the signal and idler beams maintain a significant amount of quantum correlations. The dependance of the quantum correlation on the pump intensity has been characterized across the parametric instability threshold, showing the regime here the non-classical features are maximized.
