Abstract: An organic solid crystal (OSC) thin film includes an organic crystalline phase, where the organic crystalline phase includes a chiral molecule. A chiral molecule-containing organic solid crystal thin film may have a refractive index and birefringence that can be actively tuned via charge injection. An organic solid crystal thin film including a single enantiomer of a chiral organic molecule may be configured to propagate a selected handedness of circularly polarized 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.

Abstract: A thin film includes a solid organic phase containing an amino acid scaffold and an anisotropic organic molecule. A method includes forming a thin film including a derivatized amino acid, the derivatized amino acid including an amino acid scaffold and an organic molecule, forming a primary electrode over a first portion of the thin film, forming a secondary electrode over a second portion of the thin film, and changing a biased state between the primary electrode and the secondary electrode in an amount effective to change an optical property of the thin film.

Abstract: A multilayer reflective polarizer includes a layer of a birefringent organic solid crystal, where the birefringent organic solid crystal has a refractive index of at least approximately 1.5 and a birefringence of at least approximately 0.1. The multilayer reflective polarizer may be configured to include alternating layers of a birefringent organic solid crystal material and a secondary material layer selected from an amorphous polymer, an inorganic amorphous compound, a liquid crystal, and an OSC material. The refractive index of the birefringent organic solid crystal layer(s) may be modified through the application of an applied voltage, current, or stress.
