Controlling the hidden parity in vectorial light with metasurfaces

Abstract

Vectorial states of light, where the polarization is inhomogeneously distributed in space, have gained considerable interest in the context of structured light, but their inherent parity has hitherto been overlooked. Now, parity has been revealed as a fundamental degree of freedom in vectorial light that can be acted on with customized metasurfaces, opening a path to high capacity classical and quantum communication.
