Original Abstract Submitted
in some embodiments, a head-mounted augmented reality display system comprises one or more hybrid waveguides configured to display images by directing modulated light containing image information into the eyes of a viewer. each hybrid waveguide is formed of two or more layers of different materials. a first (e.g., thicker) layer is a highly optically transparent core layer, and a second (e.g., thinner) auxiliary layer includes a pattern of protrusions and indentations, e.g., to form a diffractive optical element. the pattern may be formed by imprinting. the hybrid waveguide may include additional layers, e.g., forming a plurality of alternating core layers and thinner patterned layers. multiple waveguides may be stacked to form an integrated eyepiece, with each waveguide configured to receive and output light of a different component color.
