| contents | Exciton-polaritons, hybrid photon-exciton quasiparticles, constitute a useful platform for the study of light-matter interaction and nonlinear photonic applications. In this work, we realize a monolithic Tamm-plasmon microcavity embedding a thin film of two-dimensional halide perovskites with a tunable polymer spacer that controls the exciton-photon detuning. Angle-resolved optical spectroscopy at room temperature reveals the lower polariton branch dispersions in the linear regime for several detunings. Under circularly polarized, non-resonant laser excitation, the spin injection of high-energy excitons and their relaxation towards the lower polariton branch demonstrates its preservation, in contrast to the bare exciton case. The spin-polarized emission survives due to the fast decay of polaritons. Our results provide promising insights into the non-resonant spin control of polaritonic devices, including chiral lasers and switches. |
