Mots-clés : Exciton Polariton Microcavité Spectroscopie Semiconducteur Interaction In this review, we will try to summarize the results that we have obtained on the measurement of polariton interactions. We will describe here the samples, the experimental systems and some of the important results. We will also give a few highlights on the theoretical description of these results. One of the mai...

Total Polarisation Conversion in Two-dimensional Electron System under Cyclotron Polariton Resonance Conditions

The polarisation conversion of a linear polarized electromagnetic wave incident onto a two-dimensional (2D) electron system at an angle θ is theoretically studied. We consider the 2D system located at the interface between two dielectric media with different dielectric constants. An external dc magnetic field is assumed to be directed along the normal to the 2D electron layer. In such a configu...

Exciton-polariton gap solitons in two-dimensional lattices.

We report on the two-dimensional gap-soliton nature of exciton-polariton macroscopic coherent phases (PMCP) in a square lattice with a tunable amplitude. The resonantly excited PMCP forms close to the negative mass M point of the lattice band structure with energy within the lattice band gap and its wave function localized within a few lattice periods. The PMCPs are well described as gap solito...

Electron-polariton scattering in semiconductor microcavities.

In semiconductor microcavities, electron-polariton scattering has been proposed as an efficient process that can drive polaritons from the bottleneck region to the ground state, achieving Bose amplification of the optical emission. We present clear experimental observation of this process in a structure that allows control of the electron density and we report substantial enhancement of photolu...
