Abstract

The SPAD device comprises a single-photon avalanche diode and a further single-photon avalanche diode having breakdown voltages, the single-photon avalanche diodes being integrated in the same device. The breakdown voltages are equal or differ by less than 10%. The single-photon avalanche diode is configured to enable to induce triggering or to have a dark count rate that is higher than the dark count rate of the further single-photon avalanche diode.
