Abstract: An optical device includes a first polarization selective reflector; and a second polarization selective reflector positioned relative to the first polarization selective reflector so that the first polarization selective reflector directs first light having a first polarization toward the second polarization selective reflector and the second polarization selective reflector directs second light having a second polarization toward the first polarization selective reflector. A first plane defined by the first polarization selective reflector intersects a second plane defined by the second polarization selective reflector at a first angle.

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: 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: A waveguide display includes a substrate transparent to at least one of visible or near infrared light, and a grating on the substrate. The grating includes ridges formed using a birefringent material and is configured to selectively couple incident light in a first polarization state into or out of the substrate. The birefringent material in the ridges is characterized by an optic axis parallel to a plane that includes a grating vector of the grating.

Abstract: A method of forming an organic solid crystal (OSC) thin film includes forming a layer of a non-volatile medium material over a surface of a mold, forming a layer of a molecular feedstock over a surface of the non-volatile medium material, the molecular feedstock including an organic solid crystal precursor, forming crystal nuclei from the organic solid crystal precursor, and growing the crystal nuclei to form the organic solid crystal thin film. An organic solid crystal (OSC) thin film may include a biaxially-oriented organic solid crystal layer having mutually orthogonal refractive indices, n1≠n2≠n3.

Abstract: A pupil-replicating lightguide includes a slab of transparent material, a switchable out-coupling grating for out-coupling portions of image light to propagate towards an eyebox, and a switchable tracking grating for redirecting tracking light carrying an eye image towards an eye tracking camera. One of the two gratings may be turned ON while the other is turned OFF, in a time-sequential manner, allowing the combined use of the pupil-replicating lightguide for carrying image light and eye tracking light.

CPC classification number: G02B5/3016 , G02B1/08
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.

Abstract: A light-emitting diode includes a first semiconductor region of one of p- or n-conductivity types, a second semiconductor region of the other one of p- or n-conductivity types, forming a p-n junction with the first semiconductor region, and a quantum well layer at the p-n junction between the first and second semiconductor regions. A hyperbolic metamaterial structure is provided in the second semiconductor region. The hyperbolic metamaterial structure is coupled to the quantum well layer for extracting light from the quantum well layer. The hyperbolic metamaterial structure may be patterned to provide an array of nanoantennas to apodize the emitted beam, and to control the polarization state of the emitted beam.
