Here, we demonstrate the control of an artificial\nRashba-Dresselhaus (RD) SOC mediated by photochemical reactions in a\nmicrocavity filled with an organic single-crystal of photochromic phase-change\ncharacter. Splitting of the circular polarization components of the optical\nmodes induced by photonic RD SOC is observed experimentally in momentum space.\nBy applying an ultraviolet light beam, we control the spatial molecular\norientation through a photochemical reaction and with that we control the\nenergies of the photonic modes. This way we realize a reversible conversion of\nspin-splitting of the optical modes with different energies, leading to an\noptically controlled switching between circularly and linearly polarized\nemission from our device. Our strategy of in situ and reversible engineering of\nSOC induced by a light field provides a promising approach to actively design\nand manipulate synthetic gauge fields towards future on-chip integration in\nphotonics and topological photonic devices.","lang":"eng"}]}
