Abstract
Many applications require photodetectors with single-photon sensitivity and high timing resolution. We present a module based on a linear array of 32 Single-Photon Avalanche Diodes (SPADs) for multi-channel Time-Correlated Single-Photon Counting (TCSPC) applications. Each pixel includes a 30 μm active area diameter SPAD and quenching and counting electronics. We measured a timing resolution of about 110 ps, a photon detection efficiency of 40% at λ = 420 nm and a very low dark count rate of about 150 cps at room temperature.
