    Abstract: An anti-reflective waveguide assembly comprising a waveguide substrate having a first index of refraction, a plurality of diffractive optical elements disposed upon a first surface of the waveguide and an anti-reflective coating disposed upon a second surface of the waveguide. The anti-reflective coating preferably increases absorption of light through a surface to which it is applied into the waveguide so that at least 97 percent of the light is transmitted. The anti-reflective coating is composed of four layers of material having different indices of refraction that the first index of refraction and an imaginary refractive index less than 1×10−3 but preferably less than 5×10−4.

    Abstract: Fabrication of augmented reality (AR) and mixed reality (MR) polymer eyepiece assemblies and the resulting AR/MR polymer eyepiece assemblies may include one or more features, separately or in any appropriate combination, to compensate for expected deformation and to maintain substantially uniform gaps between polymer layers. Such features include fabricating polymer eyepiece assemblies with components having coefficients of thermal expansion (CTE) that are substantially the same; modifying the surface chemistry or structure of one or more polymer layers to increase hydrophobicity or omniphobicity of the polymer layer; disposing adhesive between adjacent polymer layers in continuous and/or extended configurations; and disposing microspheres of different sizes at selected locations between polymer layers.

    Abstract: 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.

    Abstract: An example waveguide can include a polymer layer having substantially optically transparent material with first and second major surfaces configured such that light containing image information can propagate through the polymer layer being guided therein by reflecting from the first and second major surfaces via total internal reflection. The first surface can include first smaller and second larger surface portions monolithically integrated with the polymer layer and with each other. The first smaller surface portion can include at least a part of an in-coupling optical element configured to couple light incident on the in-coupling optical element into the polymer layer for propagation therethrough by reflection from the second major surface and the second larger surface portion of the first major surface. The waveguide can include a tilted surface portion forming at least part of an in-coupling optical element, the tilted surface portion having curvature to provide optical power.
