Abstract: A device includes a light source to emit light and a light detector to receive the light emitted by the light source. The device may include a high voltage optical transformer and may be configured such that the light detector is laterally spaced away from the light source. In some architectures, the light source and the light detector may be arranged in a common plane. A photonic integrated circuit may be used to couple light emitted from the light source to the light detector.

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: The disclosure includes optical systems and near-eye optical elements configured to suppress stray infrared light. Infrared illuminators illuminator an eyebox area with narrow-band infrared illumination light for eye-tracking. A combiner layer receives reflected infrared light reflected of an eye of the user and directs the reflected infrared light to a camera configured to capture eye-tracking images of an eye of a user. An anti-reflection (AR) coating may be disposed on a base curvature to reduce Fresnel reflections that generate stray light. A ghost suppression component may be paired with the infrared illuminators to reduce stray light becoming incident on the camera.

Abstract: A backlight device includes a first surface and a second surface that is opposite to the first surface. The backlight device is configured to emit light in a first optical band through the second surface toward a display panel of a head-mounted display (HMD). The display panel is configured to convert the light from the backlight device to image light. The backlight device is transparent to light in a second optical band that is different than the first optical band. An eye tracking system illuminates an eyebox with light in the second optical band. A camera assembly positioned adjacent to the first surface of the backlight device. The camera assembly is configured to capture images of the eye in the second optical band through the backlight device, the display panel. The eye tracking system determines eye tracking information based at least in part on the captured images.

Abstract: A display device includes a display panel having a first emission region and one or more second emission regions disposed adjacent to the first emission region. The display device includes a plurality of light emitters, arranged in the first emission region, corresponding to a first color gamut and a plurality of light emitters, arranged in the one or more second emission regions, corresponding to a second color gamut that is distinct from the first color gamut. A method for making a display device with a plurality of light emitters corresponding to a first color gamut in a first emission region and a plurality of light emitters corresponding to a second color gamut in a second emission region is also described.
