Polaritons are gaining attention as a new medium for spin information. In this study, we propose a method to control the handedness of circularly polarized polaritons without applying an external magnetic field, by using chiral two-dimensional perovskites. By tuning a simple parameter, the cavity length, we modulated the hybridization between excitons and photons, successfully reversing the handedness of circular polarization. The observed changes in the asymmetry coefficient provide promising evidence for spin control in polariton systems using chiral semiconductors.
