Abstract: A thermally tunable optoelectronic module includes a light emitting assembly operable to emit light of a particular wavelength or range of wavelengths. The light emitting assembly is disposed to a temperature-dependent wavelength shift. The thermally tunable optoelectronic module further includes an optical assembly aligned to the light emitting assembly, and separated from the light emitting assembly by an alignment distance. The thermally tunable optoelectronic module further includes a thermally tunable spacer disposed between the optical assembly and the light-emitting assembly, the thermally tunable spacer is operable to counteract the temperature-dependent wavelength shift.

Abstract: The present disclosure describes compact remote eye tracking systems that include depth sensing capacity. In one aspect, a method of eye tracking includes illuminating a subject's eye with illumination; detecting, in a depth sensor, optical signals reflected from the subject's face in response to the illumination; generating a depth map based on the optical signals detected by the depth sensor; acquiring an intensity image based on optical signals reflected from the subject's face in response to the illumination; determining, based on a portion of the depth map corresponding to the subject's eye, an estimated distance between the subject's eye and a target screen; determining an estimated gaze direction of the subject's eye based on information obtained from the intensity image; and determining, based on the estimated gaze direction and the estimated distance between the subject's eye and the target screen, a gaze point for the subject's eye.

Abstract: Optoelectronic modules for proximity determination and ambient light sensing include hybrid optical assemblies configured with multiple field-of-views. The field of view in a region of the hybrid optical assembly can be dedicated to a first detector, while the field of views in another region of the hybrid optical assembly can be dedicated to both the emission of light and ambient light sensing. Embodiments relate particularly to implementation in a mobile phone or other portable electronic devices.

Abstract: Imaging systems include multi-tap demodulation pixels for biometric measurements such as heart rate or blood oxygen level. Using multi-tap demodulation pixels can, in some cases, help facilitate the generation of differential signals to remove background noise and achieve a higher dynamic range for the biometric measurements.

Abstract: An imaging device, including a monolithic semiconductor integrated circuit substrate, comprises a focal plane array of pixel cells. Each one of the pixel cells includes a gate overlying a region of the substrate operable to convert incident radiation into charge carriers. The pixel also includes a CMOS readout circuit including at least one output transistor in the substrate. The pixel further includes a charge coupled device section on the substrate adjacent the gate, the charge coupled device section including a sense node to receive charge carriers transferred from the region of the substrate beneath the gate. The sense node is coupled to the output transistor. The pixel also includes a reset switch coupled to the sense node. The pixel's charge coupled device section has a buried channel region. The pixel also includes one or more bias enabling switches operable to enable a bias voltage to be applied to the gate. At least one of the reset switch or the one or more bias enabling switches is formed in the buried channel region.

Abstract: This disclosure describes optical systems for projecting an irregular or complex pattern onto a region of space (e.g., a two-dimensional or three-dimensional object or scene). A respective light beam is emitted from each of a plurality of light sources. The emitted light beams collectively are diffracted in accordance with a plurality of different first grating parameters to produce a plurality of first diffracted light beams. The first diffracted light beams then collectively are diffracted in accordance with one or more second grating parameters.

Abstract: A method of forming a wafer stack includes providing a sub-stack comprising a first wafer and a second wafer. The sub-stack includes a first thermally-curable adhesive at an interface between the upper surface of the first wafer and the lower surface of the second wafer. A third wafer is placed on the upper surface of the second wafer. A second thermally-curable adhesive is present at an interface between the upper surface of the second wafer and the lower surface of the third wafer. Ultra-violet (UV) radiation is provided in a direction of the upper surface of the third wafer to cure a UV-curable adhesive in openings in the second wafer and in contact with portions of the third wafer so as to bond the third wafer to the sub-stack at discrete locations. Subsequently, the third wafer and the sub-stack are heated so to cure the first and second thermally-curable adhesives.
