Room Temperature Broadband Polariton Lasing from a CsPbBr <sub>3</sub> Perovskite Plate
Abstract Tunable polariton lasing is demonstrated from an all‐inorganic CsPbBr 3 perovskite microcrystal plate over 23 nm in the green part of the optical spectrum, operating at room temperature. The emission spectrum is controlled by adjusting the effective length of a multi‐ planar microcavity, whilst observing the hallmarks of polariton condensation under non‐resonant excitation. Furthermore, simultaneous condensation is observed into two non‐degenerate lower polariton branches of orthogonal polarizations induced by anisotropy of the perovskite crystal.
