Abstract: An augmented reality system can include a waveguide having an edge surface that extends between opposing light-guiding surfaces. The waveguide can guide light toward the edge surface. The waveguide can include a reflectivity-reducing film, such as an absorptive film or a photovoltaic film, disposed on the edge surface. To form the reflectivity-reducing film, curable material can be disposed onto a dissolvable film. The curable material can be cured while disposed on the dissolvable film such that the cured material forms a reflectivity-reducing structure on the dissolvable film. The dissolvable film can be dissolved such that the reflectivity-reducing structure remains intact as a reflectivity-reducing film that can be adhered to the edge surface, such as with a primer layer. The edge surface can include nanostructures, sized smaller than half a wavelength of the guided light, that can reduce a reflectivity of the edge surface.

Abstract: In a thin film stack deposited on a substrate, a first layer can have a non-uniform thickness. A second layer, disposed so that the first layer is between the substrate and the second layer, can have a non-uniform thickness. A first pattern can be formed on the second layer to define first areas. The second layer can be etched in the first areas to form first holes having varying depths. A second pattern can be formed on the first layer in the first holes to define second areas. Each second area can be smaller than a corresponding first area. The first layer can be etched in the second areas to form second holes having varying depths. An imprint of the etched thin film stack can be formed such that the first holes and the second holes form a plurality of diffractive elements having varying sizes on the imprint.
