Nonclassical statistics from a polaritonic Josephson junction

TL;DR

This paper theoretically demonstrates that a polaritonic Josephson junction can produce strongly nonclassical light with antibunching due to phase and population dynamics, revealing new quantum emission properties in semiconductor systems.

Contribution

It introduces a theoretical model showing nonclassical emission statistics in a driven exciton-polariton Josephson junction, highlighting conditions for optimal intensity squeezing.

Findings

Periodically meets intensity squeezing conditions

Emergence of antibunching in semiconductor polariton systems

Nonclassical signatures detectable in emission statistics

Abstract

We theoretically study the emission statistics of a weakly nonlinear photonic dimer during coherent oscillations. We show that the phase and population dynamics allow to periodically meet an optimal intensity squeezing condition resulting in a strongly nonclassical emission statistics. By considering an exciton-polariton Josephson junction resonantly driven by a classical source, we show that a sizeable antibunching should emerge in such semiconductor system where intrinsic nonclassical signatures have remained elusive to date.
