This study successfully demonstrates the control of spin-orbit interaction of light in organic microcrystals, opening up new possibilities for future photonics and topological photonics.
The ability to control the spin-orbit interaction (SOI) of light in optical microresonators is of fundamental importance for future photonics. Organic microcrystals, due to their giant optical anisotropy, play a crucial role in spin-optics and topological photonics. Here, the controllable and wavelength-dependent Rashba-Dresselhaus (RD) SOI is realized that is attributed to the anisotropic excitonic response in an optical microcavity filled with an organic microcrystalline. This work investigates the transition of the spin-splitting from twice winding caused by the splitting of the transverse-electric and transverse-magnetic modes to once winding caused by the RD effect. The interplay of the two allows engineer the SOI of light in organic microcavities, which besides its fundamental interest promises applications in spin-controlled on-chip integrated nanophotonic elements, toward exploiting nonmagnetic and low-cost spin-photonic devices.
