Performance of new MAPD photodiodes


The article presents the results of the study of optical characteristics and the calculation of the internal gain of a new micropixel avalanche photodiode (MAPD). The calculation procedure is described, the experimental setup of the performed studies, and the results of the study of parameters at low light fluxes, up to single photons, are also presented. It was revealed that avalanche photodiodes with a micropixel structure can be silicon analogs of widely used vacuum photomultiplier tubes.
