Microlaser Achieves Optical Gain Via Spin-Helix Lasing
WARSAW, Poland, April 6, 2022 — A microlaser that is tunable in the range of 40 nm has been developed by researchers at the University of Warsaw, the Military University of Technology in Warsaw, and the University of Southampton. The broadly tunable laser emits two circularly polarized beams that are directed at different angles, due to a persistent spin helix on the surface of the laser’s microcavity. The researchers introduced optical gain into this system by dispersing a molecular dye in a liquid crystal
