The quest for realizing novel fundamental physical effects and practical applications in
ambient conditions has led to tremendous interest in microcavity exciton polaritons working …

Ultrafast all-optical switches and integrated circuits call for giant optical nonlinearity to
minimize energy consumption and footprint. Exciton polaritons underpin intrinsic strong …

We develop a comprehensive theoretical model for the interaction strength between a pair of
exciton polaritons in microcavity devices. Ab initio numerical calculations for dipolar …

Comparing with pure photons, higher nonlinearity in polariton systems has been exploited in
various proof-of-principle demonstrations of efficient optical devices based on the parametric …

Lead halide perovskites exhibit good performance in room-temperature exciton–polariton
lasers and efficient flow of polariton condensates. Sha** and directing polariton …

Optical parametric oscillators (OPOs) have been widely applied in spectroscopy, squeezed
light, and correlated photons, as well as quantum information. Conventional OPOs usually …

We introduce a scheme of single-photon emission based on four-wave mixing in a three
mode system with weak Kerr-type nonlinearity. A highly populated lower energy mode …
