Abstract

Exciton polaritons, as bosonic quasi-particles with both photon and exciton properties, provide an excellent platform for investigating novel physical effects of optical spin-orbit coupling (SOC). However, the intrinsic correlation between exciton polaritons and the spin textures evolution of the SOC lacks an intuitive explanation. Here, we demonstrate the spin textures rotation of optical SOC through the interaction of exciton and photons in organic crystal-filled microcavities with different molecular orientations. The spin textures exhibit an antisymmetric spatial distribution of left- and right-handed circularly polarized textures at wavevector k_y = 0, which is achieved via optical SOC between pure cavity photon modes in excitons and photons weak interaction systems. In contrast, in exciton-photon strong coupling microcavities, the spin textures rotate 45° due to the in-plane effective magnetic field rotation caused by the optical SOC between exciton polaritons modes and optical cavity modes. The effective manipulation of spin textures rotation of optical SOC based on exciton polaritons provides core physical mechanisms for on-chip spin photon devices, spin filtering, and quantum information manipulation.
