Abstract

Tunable polariton lasing is demonstrated from an all-inorganic CsPbBr₃ 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- $λ$ 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.

在室温下工作时，从全无机 CsPbBr3 包晶石微晶板上展示了 23 nm 以上的可调偏振子激光，其光谱为绿色部分。通过调节多 λ $bm{\lambda }$ 平面微腔的有效长度控制了发射光谱，同时观察到了非共振激发下的极化子凝聚特征。此外，还观察到在过氧化物晶体各向异性的诱导下，同时凝聚成两个正交极化的非退化下极化子分支。
