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 a housing, an optical emitter, and an optical detector. A first light guide disposed in a first chimney of the housing is configured to direct light from the optical emitter through the first chimney towards a target location. A second light guide disposed in a second chimney of the housing is configured to direct a returned portion of the light emitted from the optical emitter through the second chimney towards the optical detector.

Abstract: An optical sensor module includes a module housing defining a first compartment having a first aperture and a second compartment having a second aperture, with the second aperture spaced apart from the first aperture. A set of optical emitters is disposed in the first compartment and configured to emit light through the first aperture. A first set of optical detectors is disposed in the first compartment and configured to receive a first redirected portion of the emitted light through the first aperture. A set of optical elements is disposed in the first compartment and configured to direct at least a portion of the emitted light or the first redirected portion of the emitted light. A second set of optical detectors is disposed in the second compartment and configured to receive a second redirected portion of the emitted light through the second aperture.
