Abstract
A method of manufacturing waveguides for head mount displays may include bonding a first set of waveguide elements with one or more adhesives sensitive to thermal or chemical removal and a second set of waveguide elements with one or more adhesives insensitive to thermal or chemical removal to form a waveguide stack, cutting the waveguide stack to form waveguide structures with embedded facets or diffractive elements, and removing portions corresponding to the first set of waveguide elements using a thermal or chemical removal while portions corresponding to the second set of waveguide elements remain bonded.
