  • Patent number: 11927814
    Abstract: An optical signal to be detected enters single photon avalanche diode cells (SPAD) in a SPAD array and triggers photo event currents. Optical waveguides in the sensor carry an internal optical signal and a 1xN splitter divides the optical power into waveguide branches 206, 206?, . . . 206N-1. At the coupling structure, comprising 207, 207?, . . . 207N-1 positive-intrinsic-negative diode photodetector/waveguide structures, photo event currents from SPAD cells are converted to a change in the internal optical signal, by modifying internal optical signals 208, 208?, . . . 208N-1. A waveguide combiner further integrates the modified internal optical signals resulting from the photo event currents from all the cells in the sub-array. After all waveguide branches' signals are combined, a photodetector detects the internal optical signal and outputs an electrical signal.
