The new-type silicon photomultiplier for ToF LiDAR and other pulse detecting applications

DEPHAN detector is a prototype of a new-type silicon photomultiplier (HD-SiPM) with the amplifying channels (cells) integrated into solid photosensitive area. The new proposed design enables to increase cell density (4.5⋅10⁴ per sq. mm) and significantly widen dynamic range of the detector preserving or even improving its fill factor (>80%) and cross-talk probability (<2%). Threshold sensitivity of the "LiDAR-emulating" system for red and NIR wavelength, its dependence on background illumination, and other key characteristics were measured with the DEPHAN detector and reference detectors (APD, SiPM). Results confirm prospects of the new-type detector for ToF-LiDAR and 3D-imaging systems.
