Alexey Taradin and Denis G. Baranov 2, ∗ Center for Photonics and 2D Materials, Moscow Institute of Physics and Technology, Dolgoprudny 141700, Russia Department of Physics, Chalmers University of Technology, 412 96, Göteborg, Sweden Abstract Geometrical chirality is a universal phenomenon that is encountered on many different length scales ranging from geometrical shapes of various living organisms to protein and DNA molecules. Interaction of chiral matter with chiral light that is, electromagnetic field possessing a certain handedness underlies our ability to discriminate enantiomers of chiral molecules. In this context, it is often desired to have an optical cavity that would efficiently couple to only a specific (right or left) molecular enantiomer, and not couple to the opposite one. Here, we demonstrate a singlehandedness chiral optical cavity supporting only an eigenmode of a given handedness without the presence of modes of other helicity. Resonant excitation of the cavity with light of appropriate handedness enables formation of a helical standing wave with a uniform chirality density, while the opposite handedness does not cause any resonant effects. Furthermore, only chiral emitters of the matching handedness efficiently interact with such a chiral eigenmode, enabling the handednessselective coupling light-matter strength. The proposed system expands the set of tools available for investigations of chiral matter and opens the door to studies of chiral electromagnetic vacuum.
