Abstract
Disclosed herein are display and photonic devices utilizing metasurfaces. An optical device comprising an optical component and an optical transmission medium is disclosed. A waveguide couples the optical component and the optical transmission medium. A metasurface is disposed on an end of the waveguide and arranged to increase an optical coupling between the waveguide and the optical transmission medium. Additionally, a display comprising a number of light emitting elements and a metasurface for each of the light emitting elements. The metasurface arranged to eliminate screen door effect in virtual reality display systems.
