An optical metasurface to interact with incoming light, wherein the metasurface is comprising

a transparent substrate comprising a plurality of nano-holes or nano-pillars, wherein the nano-holes or nano-pillars have vertical or substantially vertical side walls extending perpendicular to a base plane of the substrate, and
a plurality of shaped layers comprising a transparent dielectric material, wherein each shaped layer covers a plurality of the nano-holes or the nano-pillars of the transparent substrate.

A method for producing an optical metasurface for interacting with incoming light, wherein the method is comprising:

providing a transparent substrate comprising a plurality of nano-holes or nano-pillars, wherein the nano-holes or nano-pillars have vertical or substantially vertical side walls extending perpendicular to a base plane of the transparent substrate, and
covering at least a portion of the transparent substrate with shaped layers of a transparent dielectric material so that each shaped layer covers a plurality of the nano-holes or nano-pillars of the transparent substrate.
