Electrically-controlled dynamic optical component comprising a planar metasurface

Abstract

An optical component comprising a planar metasurface arranged on a surface of a first substrate and a top layer arranged in a height direction Z above the metasurface, wherein the metasurface comprises a plurality of scattering structures, wherein a dielectric material is deposited on a subset of the plurality of scattering structures, wherein an active media is sandwiched between the metasurface and the top layer, wherein an incident electromagnetic radiation is transmitted or reflected by the optical component, wherein a phase profile modulation is induced on the incident electromagnetic radiation during the reflection or transmission.
