Polariton parametric luminescence in a single micropillar

The authors report on parametric luminescence in a single pillar semiconductor microcavity. Nonresonant photoluminescence measurements at 10 K show that micropillars operate in the exciton-photon strong coupling regime. Under resonant excitation, polariton parametric scattering is observed: signal and idler beams are of comparable intensities, a promising result in the framework of quantum optics with correlated photon pairs

Parametric polariton scattering in single micropillar microcavities

Three dimensional microresonators (micropillars) operating in the strong coupling regime were studied by photoluminescence. Parametric oscillations of 0-dimensional polaritons are evidenced on a single micropillar. Signal and idler beam are of comparable intensities, a promising result in the aim of the emission of correlated photon pairs
