Inter-pixel cross-talk as background to two-photon interference effects in SPAD arrays

Abstract Cross-talk is a well-known feature of single-photon avalanche detectors. It is especially important to account for this effect in applications involving temporal coincidences of two or more photons registered by the sensor since in this case the cross-talk may mimic the useful signal. In this work, we characterize the cross-talk of the LinoSPAD2 detector, as well as perform joint measurements of the cross-talk and Hanbury Brown-Twiss two-photon interference, comparing and cross-calibrating both effects. With a median dark count rate of 125 cps/pixel, we report the average cross-talk probability of 0.22% for the nearest neighbor and also observe a long-range cross-talk of the order 2 · 10 -5 % for channels separated by up to 20 pixels.

Abstract

Abstract Cross-talk is a well-known feature of single-photon avalanche detectors. It is especially important to account for this effect in applications involving temporal coincidences of two or more photons registered by the sensor since in this case the cross-talk may mimic the useful signal. In this work, we characterize the cross-talk of the LinoSPAD2 detector, as well as perform joint measurements of the cross-talk and Hanbury Brown-Twiss two-photon interference, comparing and cross-calibrating both effects. With a median dark count rate of 125 cps/pixel, we report the average cross-talk probability of 0.22% for the nearest neighbor and also observe a long-range cross-talk of the order 2 · 10 -5 % for channels separated by up to 20 pixels.
