Four wave mixing oscillation in a semiconductor microcavity: Generation of two correlated polariton populations

TL;DR

This paper reports the discovery of a new four wave mixing oscillation in semiconductor microcavities, producing two correlated polariton populations with distinct spatial and polarization characteristics, confirmed by fluctuation measurements.

Contribution

It introduces a novel polariton four wave mixing oscillation and demonstrates strong correlations between the generated polariton populations.

Findings

Observation of two spatially and polarization-separated beams

Strong intensity correlations between the two beams

Confirmation of correlated polariton populations

Abstract

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 spatially and in polarization with respect to the pumps. The measurement of the intensity fluctuations of the emitted light demonstrates that the final states are strongly correlated.
