The authors report on parametric luminescence in a single pillar semiconductor microcavity. Nonresonant photoluminescence measurements at 10K 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.
