Paper Abstract

We present a multichannel photon counting module that exploits a monolithic array of single-photon avalanche diodes (SPADs). The detector array consists of eight 50μm diameter SPADs featuring low dark counting rate and high photon detection efficiency (50% at 550nm); inter-pixel crosstalk probability is as low as 2•10-3. The use of highly integrated active quenching circuits makes it possible to design a very compact read-out circuit, yet providing eight fully independent counting channels and gating capability. The detection module maintains the same physical dimensions of commercially available single element modules and can be used as a plug-in replacement to add multichannel capabilities to existing measurement setups. Full characterization of module performance is here presented.
