Optically Trapped Exciton‐Polariton Condensates in a Perovskite Microcavity
Source abstract
Abstract
Abstract Room temperature optical trapping and generation of high‐order angular harmonics are demonstrated in exciton‐polariton condensates in a monocrystalline CsPbBr3 perovskite‐filled microcavity. Using an annular nonresonant excitation profile focused onto the perovskite, power‐driven switching is observed between different transverse modes of the optically induced trap. The interplay is explored between the perovskite crystal dimensions and the optical trap diameter that allows the condensate to transition from whispering gallery‐like petal shapes to ripple states. These results underline the feasibility in creating high‐order quantum states in perovskite polariton condensates for reconfigurable and structured room temperature nonlinear lasing.
