Since their first demonstration in 1960, lasers have been tremendously influential in almost all aspects of scientific research, industrial manufacturing, and in the medical, military, and engineering fields. Whereas an optical laser generates coherent light beams amplified through stimulated emission from a cavity filled with various gain media, a polariton laser is a device that emits coherent electromagnetic waves from a cavity with embedded quantum wells. Coherent polaritons at the system ground state are amplified by stimulated scattering processes to undergo Bose-Einstein condensation. This article explains basic structures, fundamental operating principles, and several types of polariton-based light sources.
