Abstract
Embodiments described herein relate to apparatus and methods for display structure fabrication. In one embodiment, a waveguide structure having an input grating structure and an output grating structure is fabricated and a spacer material is deposited on the waveguide. The spacer material is etched from various portions of the waveguide structure and a high refractive index material is deposited on the waveguide. Portions of the spacer material remaining on the waveguide structure are removed leaving the high refractive index material disposed on desired surfaces of the waveguide structure.
