Abstract: There is provided an optical sensor including a photodiode, a wave converter, a pixel array and a processor. The photodiode detects ambient light flicker to generate sine waves. The wave converter converts the sine waves to square waves. The processor uses a sampling frequency to count the square waves, and identifies whether the ambient light flicker is well detected according to a counting value of each square wave and a counting value variation of multiple square waves within a count period to accordingly determine whether to recognize a frequency of ambient light flicker and adjust an acquiring phase of the image frame.

Abstract: A light detection apparatus is provided which improves quantum efficiency QE while suppressing light color mixing. The apparatus has multiple pixels including a first and a second pixel, the first pixel receiving, out of incident light thereon, either full-spectrum light or light having a peak wavelength in a wavelength region equal to or higher than a predetermined wavelength, the second pixel receiving, out of the incident light thereon, light having a peak wavelength in a wavelength region lower than the predetermined wavelength. The distances between the widthwise centers of multiple cross sections of the light blocking film in parallel with the light receiving surface of the substrate, the cross sections being perpendicular to the light receiving surface, are first distances each constituting the same distance. The distance between the widthwise centers of two cross sections of the pixel separation part that are perpendicular to the light receiving surface of the substrate and positioned surrounding the photoelectric conversion part in the first pixel is a second distance different from the first distance.

Abstract: A system and method for detection, localization and signaling of single photon events and of at least two photons time coincidence events. The system includes at least one array of pixels, each of which includes a photodetector and a front-end electronics, which outputs a digital signal; at least one event detection electronics including: a plurality of digital-to-analog transducers, one for each pixel of the array, configured to convert the digital signal coming from the respective pixel in a corresponding analog signal, which is quantized in amplitude and duration; an analog adder node configured to sum the analog signals coming from the digital-to-analog transducers, obtaining a sum analog signal; and an overall analog-to-digital transducer. The system and method are ultimately configured to output a digital signal if an output signal of an analog adder node exceeds, respectively, a first threshold or the second threshold, allowing event detection, within a time window.

Abstract: Various embodiments of the present disclosure are directed towards an integrated chip. The integrated chip includes a first pixel region and a second pixel region within a substrate. A first recess region is disposed along a back-side of the substrate within the first pixel region. The back-side of the substrate within the first pixel region is asymmetric about a center of the first pixel region in a cross-sectional view. A second recess region is disposed along the back-side of the substrate and within the second pixel region. The back-side of the substrate within the second pixel region is asymmetric about a center of the second pixel region in the cross-sectional view. The first recess region and the second recess region are substantially symmetric about a vertical line laterally between the first pixel region and the second pixel region.

Abstract: A method of resolving a number of photons received by a photon detector includes optically coupling a waveguide to a superconducting wire having alternating narrow and wide portions; electrically coupling the superconducting wire to a current source; and electrically coupling an electrical contact in parallel with the superconducting wire. The electrical contact has a resistance less than a resistance of the superconducting wire while at least one narrow portion of the superconducting wire is in a non-superconducting state. The method includes providing to the superconducting wire, from the current source, a current configured to maintain the superconducting wire in a superconducting state in the absence of incident photons; receiving one or more photons via the waveguide; measuring an electrical property of the superconducting wire, proportional to a number of photons incident on the superconducting wire; and determining the number of received photons based on the electrical property.
