Original Abstract Submitted
Embodiments of the present disclosure generally relate to augmented reality waveguide combiners. The waveguides includes a waveguide substrate, having a substrate refractive index (RI) n, a slab waveguide layer disposed over the waveguide substrate, the slab waveguide layer having a slab RI nand a slab depth d, the slab depth dfrom a lower surface to an upper surface of the slab waveguide layer, at least one grating defined by a plurality of grating structures, the grating structures are disposed in, on, or over the slab waveguide layer, and a superstrate between and over the grating structures, the superstrate having a superstrate RI nand an interface with the slab waveguide layer. The slab RI nis greater than the substrate RI nand the slab RI nis greater than the superstrate RI n.
