Schematic diagram of the liquid crystal microcavity structure with CsPbBr3 inserted as the active layer. The anisotropy of the liquid crystal can induce spin-orbit coupling of the polariton modes and split the polaritons with opposite spins, which is measured in the circularly polarized light emitted from the microcavity.
