Abstract:
A nano-structure layer is disclosed. The nano-structure layer includes a plurality of nano-photonic structures that are configured in a first configuration such that light incident upon the nano-structured layer below a cutoff angle passes through the nano-structured layer and light incident upon the nano-structured layer above the cutoff angle is reflected back in direction of the incidence.
