==Original Abstract Submitted==

an augmented-reality (ar) eyewear display utilizes an optical waveguide having multi-layered optical gratings in a repeating arrangement. the optical gratings include varying depths, slope angles, lengths, and/or widths in order to tune the gratings to provide an improved ar eyewear display. by using the different configurations of two-dimensional or three-dimensional gratings disclosed herein in a waveguide of an ar eyewear display, optical characteristics of the waveguide are optimized to provide, e.g., high resolution and/or contrast, high display uniformity, high input coupling efficiency, and/or high output coupling efficiency. accordingly, in some embodiments, aspects of the present disclosure enable lower-power ar eyewear displays to produce the same quality of display of a higher-power conventional ar eyewear display waveguide.
