Claim 0:
1. An optical system for a see-through display, the system comprising:
a stack of metasurface (MS) layers configured to receive light constituting an image; and
a waveguide (WG) coupled to the stack,
wherein each layer in the stack of MS layers is configured to provide a resonant response that enhances an interaction amplitude of an optical field at a different spectral band and to couple the resonant response with a WG, wherein the WG is configured to propagate the different spectral bands in a direction of a user's eye;
wherein each layer in the stack of MS layers comprises nano-structures made of a different material, wherein the different material is different metal or dielectric material, and wherein the nano-structures of at least one layer of the stack of MS layers are configured to have an asymmetrical shape.
