source：optics.orgScientists from the University of Warsaw, the Military University of Technology, Poland, and the University of Southampton, UK, have developed a new type of tunable microlaser emitting two beams. “The beams are polarized circularly and directed at different angles,” explained Prof. Jacek Szczytko from Warsaw.This result was obtained by creating a “persistent-spin helix” on the surface of the microcavity. The achievement is described in Physical Review Applied.The scientists filled the optical microcavity with a liquid crystal doped with an organic laser dye. The microcavity co...
