摘要

Abstract

The complex degrees of freedom of light

such as amplitude

phase

polarization

and orbital angular momentum

make it a prime candidate for use in optical security and encryption. By exploiting the unique characteristics of metasurfaces

exciting new optical security platforms have been demonstrated.
