Stochastic pumping of a polariton fluid

TL;DR

This paper explores how different stochastic light sources affect a polariton laser's behavior, revealing that thermal statistics can significantly alter transmission, noise, and threshold properties, with potential counterintuitive effects.

Contribution

It introduces the impact of thermal and displaced thermal light statistics on polariton laser response, a novel approach compared to traditional coherent pumping studies.

Findings

Thermal statistics significantly change transmitted intensity and noise.

Adding photons can reduce transmission unexpectedly.

Response varies with correlation times of the driving light.

Abstract

We investigate the response of a polariton laser driven slightly off-resonantly using light fields differing from the routinely studied coherent pump sources. The response to driving light fields with thermal and displaced thermal statistics with varying correlation times shows significant differences in the transmitted intensity, its noise, and the position of the nonlinear threshold. We predict that adding more photons on average may actually reduce the transmission through the polariton system.
