Abstract: An optical element includes a transparent layer, outcoupling elements, and a waveguide structure. The outcoupling elements are positioned across the transparent layer. The waveguide structure provides non-visible light to the outcoupling elements and the outcoupling elements outcouple the non-visible light as non-visible illumination light to illuminate an eye region.

Abstract: A near-eye optical element includes one or more infrared light sources and an optical structure. The one or more infrared light sources emit infrared beams. The optical structure includes an optically transparent material disposed over the emission aperture(s) of the infrared light source(s). The optical structure includes one or more facets that diverge the infrared beams.

Abstract: A polymer thin film includes polyethylene having a weight average molecular weight of at least approximately 500,000 g/mol, where the thin film is characterized by transparency within the visible spectrum of at least approximately 80%, bulk haze of less than approximately 5%, and an in-plane elastic modulus of at least approximately 10 GPa. The polymer thin film may be thermally conductive and may be incorporated into an optical element and configured to dissipate heat, such as from a light-emitting device.

Abstract: An organic thin film includes an organic solid crystal material and has mutually orthogonal refractive indices, nx, ny, and nz each having a value at 589 nm of between approximately 1.5 and approximately 2.6, where nx≠ny≠nz. The organic thin film may be birefringent, and may be configured as a single layer thin film, or plural organic thin films may be stacked to form a multilayer that may be incorporated into an optical element, such as a reflective polarizer.

Abstract: A transparent optical element may include a layer of an electroactive ceramic disposed between transparent electrodes, such that the electrodes are each oriented perpendicular to a non-polar direction of the ceramic layer. Optical properties of the optical element, including transmissivity, haze, and clarity may be improved by the application of a voltage to the electroactive ceramic, and an associated phase transformation.

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: A solar reflective coating includes a reflective layer and a black layer overlying the reflective layer, where the black layer includes active particles dispersed throughout a matrix. Example active particles include phosphor microcrystals adapted to reflect incident non-visible radiation and convert incident visible radiation to non-visible radiation.

Abstract: An electromechanical actuator includes a primary electrode, a secondary electrode overlying at least a portion of the primary electrode, and an electroactive layer disposed between the primary electrode and the secondary electrode, where the electroactive layer has a first curvature when zero voltage is applied between the primary electrode and the secondary electrode, and a second curvature when a non-zero voltage is applied between the primary electrode and the secondary electrode.
