Abstract
We realize a tunable laser based on a liquid crystal optical microcavity doped with the pyrromethene 580 organic dye. The tunable range reaches 40 nm. By transforming the system into the Rashba-Dresselhaus coupling regime, the laser action takes place from the bottoms of two oppositely polarized valleys shifted apart in reciprocal space. Measurements of emissions in real space show the persistent spin-helix lasing, which is a consequence of the spin coherence of the system. The platform that we propose can be used in quantum communication, in which information is encoded through light polarization.
