Abstract: An optical coupling device includes a first waveguide layer, including a first semiconductor material, which is disposed over a dielectric substrate layer. A dielectric intermediate layer overlies the first waveguide layer. A second waveguide layer, which includes a different, second semiconductor material, is disposed over the dielectric intermediate layer and is patterned to define a waveguide. A first grating in the second waveguide layer diffracts light of a given wavelength from the waveguide into a specified diffraction order at a given coupling angle, whereby a first fraction of the light propagates out of the device while a second fraction of the light is diffracted into the intermediate dielectric layer in a conjugate diffraction order. A second grating in the first waveguide layer diffracts the second fraction of the light into a second diffraction order, propagating out of the device at the given coupling angle.

Abstract: A display may include an optical emitter that emits infrared light, a first coupler that couples the infrared light into a waveguide, and a second optical coupler that couples the infrared light out of the waveguide and towards the eye box. The infrared light may reflect off an eye as reflected light. The second optical coupler may couple the reflected light into the waveguide and the first optical coupler may couple the reflected light out of the waveguide and towards a camera for performing gaze tracking operations based on the sensor data. The display may sequentially illuminate different regions of the eye with the infrared light at different times using a scanning mirror, an array of light sources, or a wavelength-adjustable light source and gratings. This may minimize infrared light scattering, which minimizes background generation and maximizes signal-to-noise ratio for gaze tracking operations.

Abstract: An optical sensing device includes a planar substrate and an array of optical transceivers disposed on the planar substrate. Each optical transceiver includes a photodetector, at least one turning mirror having a reflective surface disposed diagonally relative to the substrate, and multiple waveguides disposed parallel to the substrate. The waveguides include a transmit waveguide, which is coupled to convey outgoing light from a coherent light source to the at least one turning mirror for output from the optical transceiver, and a receive waveguide, which is coupled to receive incoming light reflected by the at least one turning mirror and to convey the incoming light to the photodetector.

Abstract: An electronic device includes a microphone, an array of coherent optical emitters, an array of balanced coherent optical vibration sensors, and a processor. Each balanced coherent optical vibration sensor in the array of balanced coherent optical vibration sensors is paired with a coherent optical emitter in the array of coherent optical emitters. The processor is configured to analyze a set of waveforms acquired by the array of balanced coherent optical vibration sensors; identify, using the analysis of the set of waveforms, a set of one or more voices in a field of view; and adjust an output of the microphone to accentuate a particular voice in the set of one or more voices.

Abstract: A method for optical sensing includes providing a mirror comprising a central reflective region surrounded by a peripheral glare-suppressing region. A beam of light from a laser light source is directed to reflect from the central region so as to pass through an output optic along an axis toward a target scene. The light returned from the target scene through the output optic is focused onto an optical sensor, via collection optics having a collection aperture surrounding the mirror.

Abstract: An optical device includes a light source, which is configured to emit a beam of light, and a sensor having a detection area. At least one scanning mirror is configured to scan the beam across a target scene. Light collection optics include a collection lens positioned to receive the light from the scene that is reflected from the at least one scanning mirror and to focus the collected light onto a focal plane, and a non-imaging optical element having a front surface positioned at the focal plane of the collection lens and a rear surface in proximity to the sensor and configured to spread the light focused by the collection lens over the detection area of the sensor.
