The Single-photon detectors and applications laboratory of the Politecnico di Milano (PoliMi) works on single-photon avalanche diode (SPAD) detectors. The group designs and develops silicon and InGaAs SPAD detectors, and exploits them in various applications, with custom solutions. PoliMi participates in technical work-packages WP1 and WP2 based on its expertise in the design, characterization and exploitation of single-photon detectors and associated electronics, in particular for the near-infrared wavelength range (up to 1700 nm).
