Abstract :
The fact that the time resolution of single photon avalanche diodes (SPADs) is mainly dependent on the size of the detector area is demonstrated. The larger the detector is, the worse the time resolution is. This result is related to the avalanche physics and sets the ultimate performance of these devices in single-photon timing.
