Room-temperature continuous-wave pumped exciton polariton condensation in a perovskite microcavity.

ABSTRACT: Microcavity exciton polaritons (polaritons) as part-light part-matter quasiparticles garner considerable attention for Bose-Einstein condensation at elevated temperatures. Recently, halide perovskites have emerged as promising room-temperature polaritonic platforms because of their large exciton binding energies and superior optical properties. However, currently, inducing room-temperature nonequilibrium polariton condensation in perovskite microcavities requires optical pulsed excitations with high excitation densities. Here, we demonstrate continuous-wave optically pumped polariton condensation with an exceptionally low threshold of ~0.53 W cm^-2 and a narrow linewidth of ~0.5 meV. Polariton condensation is unambiguously demonstrated by characterizing the nonlinear behavior and
