Abstract: A waveguide includes a plurality of sets of layers arranged in a stack. Each set of layers includes a first layer that comprises at least tantalum and oxygen, and a second layer that comprises at least silicon and oxygen. The waveguide is configured to propagate light associated with a particular wavelength in a first direction that is orthogonal to a second direction in which the plurality of sets of layers are arranged in the stack. A quantity of the plurality of sets of layers is greater than or equal to 15. Respective thicknesses of the first layer and the second layer, in the second direction, are less than or equal to a fifteenth of the particular wavelength.

Abstract: An optical device includes an optical sensor, one or more diffusive optical elements disposed on a surface of a display screen and configured to diffuse and to distribute a first portion of light associated with a subject across an array of sensor elements of the optical sensor, and one or more processors. The display screen includes one or more transmissive components that allow the first portion of light to pass through the display screen via the surface of the display screen, and one or more blocking components that prevent a second portion of light associated with the subject from passing through the display screen. The one or more processors are configured to obtain, from the optical sensor, sensor data associated with the first portion of light, process the sensor data to determine an image of the subject, and perform one or more actions based on the image of the subject.

Abstract: An optical sensor device may include an optical sensor that includes a set of sensor elements; an optical filter that includes one or more channels; a phase mask configured to distribute a plurality of light beams associated with a subject in an encoded pattern on an input surface of the optical filter; and one or more processors. The one or more processors may be configured to obtain, from the optical sensor, sensor data associated with the subject and may determine a distance of the subject from the optical sensor device. The one or more processors may select, based on the distance, a processing technique to process the sensor data, wherein the processing technique is an imaging processing technique or a spectroscopic processing technique. The one or more processors may process, using the selected processing technique, the sensor data to generate output data and may provide the output data.

Abstract: A sputtering system may inject hydrogen and a sputtering gas into a chamber of the sputtering system, which may cause at least one layer of a hydrogenated semiconductor material, such as hydrogenated silicon (Si:H), to be sputtered onto a substrate disposed in the chamber until the at least one layer has a thickness that satisfies a threshold. In some implementations, the hydrogen and the sputtering gas may be injected into the chamber of the sputtering system while a temperature in the chamber is in a range from 145 degrees Celsius to 165 degrees Celsius. Accordingly, in some implementations, the sputtered layer of the hydrogenated semiconductor material may have one or more optical properties that satisfy a threshold to enable operation in a 9xx nanometer wavelength regime and at larger wavelengths.

Abstract: An optical filter may include a substrate. The optical filter may include a first mirror. The optical filter may include a second mirror. The optical filter may include a spacer. The first mirror, the second mirror, and the spacer may form a plurality of component filters. A first component filter, of the plurality of component filters, may be associated with a first cross-sectional area and a second component filter, of the plurality of component filters, is associated with a second cross-sectional area. The first cross-sectional area and the second cross-sectional area may be configured to response balance the first component filter and the second component filter.
