Abstract
Embodiments are disclosed for an optical waveguide display configured for use with a near-eye display (NED) device. In an embodiment the waveguide display includes a light-transmissive substrate and an optical coupling element configured to input light rays to the substrate or output light rays from the substrate, the optical coupling element configured to deflect a plurality of wavelengths of an incident light ray collinearly for propagation within the light-transmissive substrate through total internal reflection (TIR). The optical coupling element can include a pattern of nano-structures that collectively form a metasurface on the substrate.
