Abstract: A multilayer organic thin film includes a plurality of biaxially-oriented layers, where each layer is characterized by mutually orthogonal refractive indices, n1≠n2≠n3. In example structures, the corresponding in-plane refractive indices of adjacent layers may be rotated with respect to each other by a predetermined angle. Such a multilayer may be incorporated into a circular reflective polarizer, for example, which may be used in display systems to provide high broadband efficiency and high off-axis contrast. In an example process, individual organic thin films may be molded, and then oriented and stacked to form a multilayer.

Abstract: An optical element includes a waveguide body that is configured to guide light by total internal reflection from an input end to an output end, an input coupling element located at the input end for coupling light into the waveguide body, and an output coupling element located at the output end for coupling light out of the waveguide body, where the waveguide body includes an organic solid crystal. The organic solid crystal may be a single crystal having principal axes rotated with respect to the dimensions of the waveguide body. Such an optical element may have low weight and exhibit good color uniformity while providing polarization scrambling of the guided light.

Abstract: An optical film includes a plurality of helically arranged liquid crystals and organic solid crystal structures at least partially surrounding the plurality of helically arranged liquid crystals. A method of making the optical film includes obtaining a substrate with an alignment layer and a film of a first solution on the alignment layer. The first solution includes liquid crystals and organic crystal molecules. The liquid crystals form a plurality of helically arranged liquid crystals on the alignment layer. The method also includes forming organic solid crystal structures by crystallizing the organic crystal molecules. The organic solid crystal structures at least partially surround the plurality of helically arranged liquid crystals.

Abstract: An optical element (e.g., a lens) may include an optically uniaxial or optically biaxial organic solid, for example, an organic molecular solid. The direction of a maximum refractive index of the organic solid may be aligned substantially orthogonal to an optical axis of the lens. In some examples, a device may include a display and an optical configuration configured to receive light from the display and direct the light to a remote view location. In some examples, the optical configuration may comprise a lens and at least one surface of the lens may include a plurality of facets, for example, to form a Fresnel lens.
