Abstract
Systems and methods to improve efficiency of in-coupling electromagnetic waves, such as in a visible light wavelength range, into a waveguide system arrangement are disclosed. The waveguide system includes: a display or an illumination assembly; a waveguide substrate; a polarization volume grating or a spin-dependent bifacial metasurface as in-coupler, which efficiently couples electromagnetic waves, such as in a visible light wavelength range, into the waveguide substrate. An out-coupler can couple the electromagnetic waves, such as in a visible light wavelength range, out of the waveguide substrate.
