Parametric polariton amplification in semiconductor microcavities
Gaëtan Messin, Jean-Philippe Karr, Augustin Baas +5
We present novel experimental results demonstrating the coherence properties of the nonlinear emission from semiconductor microcavities in the strong coupling regime, recently inte…
Four wave mixing oscillation in a semiconductor microcavity: Generation of two correlated polariton populations
Marco Romanelli, Charles Leyder, Jean-Philippe Karr +2
We demonstrate a novel kind of polariton four wave mixing oscillation. Two pump polaritons scatter towards final states that emit two beams of equal intensity, separated both spati…
Quantum degeneracy of microcavity polaritons
Augustin Baas, Jean-Philippe Karr, Marco Romanelli +2
We investigate experimentally one of the main features of a quantum fluid constituted by exciton polaritons in a semiconductor microcavity, that is quantum degeneracy of a macrosco…
