Maximum Chirality Achieved with Resonant Dielectric Metastructures

Resonant dielectric metastructures provide a game-changing platform for chiral optics: maximum-chiral metasurfaces are transparent to waves of a particular circular polarization and strongly interact with waves of the opposite polarization. High-quality chiral resonances enhance selectively diverse nonlinear optical transformations of circularly polarized light. Stacking chiral and achiral metasurfaces and mirrors one can build optical cavities which selectively detect/emit chiral light and open a door to chiral polaritonics and chiral electromagnetic vacuum prospectively facilitating chiral chemistry.
