    Abstract: A device includes a display stack and an optical receiver. The display stack includes a set of opaque elements defining a translucent aperture. The translucent aperture extends through the display stack. The optical receiver is spaced apart from and behind a back surface of the display stack. At least one micro-optic element is formed on the back surface of the display stack, between the display stack and the optical receiver. The at least one micro-optic element includes a micro-optic element having a focal point located within the translucent aperture. The optical receiver is configured to receive light through the translucent aperture and the at least one micro-optic element.

    Abstract: A wearable device includes a device housing configured to be worn on a first surface of a user, a set of one or more SMI sensors, and a processor. The set of one or more SMI sensors is mounted within the device housing and configured to emit a set of one or more beams of electromagnetic radiation, with each beam emitted in a different direction extending away from the first surface. The set of one or more SMI sensors is also configured to generate a set of one or more SMI signals containing information about a relationship between the device housing and a second surface. The processor is configured to extract the relationship between the device housing and the second surface from digitized samples of the set of one or more SMI signals.

    Abstract: Configurations for a beam deflector metasurface are disclosed. The beam deflector metasurface may include beam deflectors arranged in a repeating, radial pattern of concentric zones. The beam deflector metasurface may be a large area, high numerical aperture metasurface optic with high efficiency when directing light at non-normal angles of incidence. The different concentric zones may direct received light in varying directions with various steepness of angles. The beam deflectors may include pillars that may be the same or different width, height, or shape. The pillars may function as diffractive gratings and the cross-coupling between the pillars may direct the output light. The zones of the beam deflector metasurface may allow for diffusing hot spots and spreading the light evenly over the target area. The beam deflector metasurface may be used for non-imaging applications where the deterioration of focus allows for better efficiency at non-normal input and output angles of incidence. The beam deflectors may be designed for polarization and wavelength sensitivity as well as allowing for multiple processing benefits such as patterning the beam deflectors onto active devices.

    Abstract: An optical proximity sensor includes an optical path extender that extends an optical path length of the optical proximity sensor without a corresponding extension of a geometric path length of the optical proximity sensor. The optical path extender may be a high-refractive index material positioned along the optical path through the optical proximity sensor. The optical path extender may include one or more redirection features configured to change a direction of the light traveling within the optical proximity sensor. The optical path extender may include a photonic component configured to simulate an extension of the geometric path within an optical proximity sensor by applying a momentum-dependent transfer function to the light traveling through it.

    Abstract: An optical sensing system includes a transmitter side and a receiver side, and is configured to be positioned below a display of an electronic device. The transmitter side includes a light emitter. The receiver side includes an array of photodiodes. The light emitter of the transmitter side and the array of photodiodes of the receiver side are optically coupled via a waveguide. As a result of this construction, the optical sensing system can be operated as an interferometric optical sensor.
