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.

Abstract: An optical film includes a block copolymer film defining a plurality of helically shaped cavities and a plurality of helically shaped organic solid crystals positioned within the plurality of helically shaped cavities. A method of making the optical film includes obtaining a film of a block copolymer solution including a chiral block copolymer and a non-chiral block copolymer on a substrate. The method includes annealing the film, thereby forming a plurality of helical structures from the chiral block copolymer defined within the non-chiral block copolymer and removing the plurality of helical structures, thereby creating a plurality of helically shaped cavities. The method further includes forming organic solid crystals inside the plurality of helically shaped cavities, thereby forming the optical film.

Abstract: An optical diffraction grating includes a layer of organic solid crystal (OSC) material, an input photonic element configured to couple an input beam to the organic solid crystal material, and an output photonic element configured to receive an output beam from the organic solid crystal material. An applied voltage may be used to control the refractive index of the OSC material and accordingly tune the operation of the optical diffraction grating.

Abstract: An actuator assembly includes a primary electrode, a secondary electrode overlapping at least a portion of the primary electrode, and an electroactive polymer layer disposed between the primary electrode and the secondary electrode, where the electroactive polymer layer includes a non-vertical (e.g., sloped) sidewall with respect to a major surface of at least one of the electrodes. The electroactive polymer layer may be characterized by a non-axisymmetric shape with respect to an axis that is oriented orthogonal to an electrode major surface.

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 organic thin film includes an organic crystalline phase, where the organic crystalline phase defines a surface having a surface roughness (Ra) of less than approximately 10 micrometers over an area of at least approximately 1 cm2. The organic thin film may be manufactured from an organic precursor and a non-volatile medium material that is configured to mediate the surface roughness of the organic crystalline phase during crystal nucleation and growth. The thin film may be formed using a suitably shaped mold, for example, and the non-volatile medium material may be disposed between a layer of the organic precursor and the mold during processing.
