Abstract

We are presenting the results of the study of various Single Photon Avalanche Diodes (SPADs) for the detection of optical signal consisting of single up to several thousands of photons. We were investigating the correlation between the avalanche buildup time and the photon number involved in the avalanche trigger. Three different detection chips made by three manufacturers were tested. The detection chips were operated in a passive quenching circuit with active gating. This setup enabled us to monitor both the diode reverse current using an electrometer and an avalanche buildup time using a fast digitizing oscilloscope. The electrometer reading enabled to estimate the photon number per detection event, the avalanche build up was recorded on the oscilloscope and processed by custom designed waveform analysis package. The correlation of avalanche build up to the photon number, bias above break, photon absorption location and optical pulse length were investigated in detail. The experimental results are presented.
