Single-Handedness Chiral Optical Cavities

Geometrical chirality is a universal property encountered on very different length scales ranging from geometrical shapes of living organisms to drug and DNA molecules. The interaction chiral matter with light, that is, an electromagnetic field possessing certain handedness, underlies our ability discriminate enantiomers In this context, it often desired have optical cavity efficiently couples only specific (right or left) molecular enantiomer does not couple the opposite one. Here, we demonstrate single-handedness supporting eigenmode given handedness lacking modes having Resonant excitation light appropriate enables formation standing wave uniform density, while cause any resonant effects. Furthermore, emitters matching interact such eigenmode, enabling handedness-selective strength light–matter coupling. proposed system expands set tools available for investigations opens door studies vacuum.
