Towards quantum correlated polariton modes in semiconductor microcavities
Résumé
In planar semiconductor microcavities in the strong coupling regime, nonlinear effects such as Kerr-like effect, parametric fluorescence and parametric oscillation are observed, as a result of parametric scattering of polaritons. After discussing the basic physical properties of the system and their theoretical description, we report on our experimental demonstration of polariton squeezing in the degenerate scattering configuration (Kerr configuration), and on the generation of correlated polaritons in the nondegenerate configuration. The latter results open the way to the generation of quantum correlated polariton modes.
