Advances in SPAD arrays propose improving the fill factor by confining several SPADs in the same well, with a main issue related to crosstalk. For measurements triggered only in well-defined time periods that can be known in advance, the pixels can be inhibited before the arrival of the crosstalk charge. This paper reports the crosstalk characterization of in an array of SPADs fabricated in a conventional CMOS technology in the same n-well (fill factor 67%). A long gating time gives a crosstalk not less than 2.75%, while reducing it below 2.5 ns completely eliminates crosstalk, as predicted by the theory and by TCAD simulations.

“…The direct calibration of the crosstalk requires either the access to the outputs of individual pixels [25][26][27] which is not possible with commercially available MPPCs, or complicated optical setups which provide illumination of individual pixels [22].…”

Abstract:We present a novel method of calibration of crosstalk probability for multi-pixel photon counters (MPPCs) based on the measurement of the normalized second-order intensity correlation function of coherent light. The method was tested for several MPPCs, and was shown to be advantageous over the traditional calibration method based on the measurements of the dark noise statistics. The method can be applied without the need of modification for different kinds of spatially resolved single photon detectors.

“…(12) was then modified according to Eqs. (4) and (6) to take into account dark-count and cross-talk contributions. We observe that the corrections introduced by the detection model are hardly perceivable, as the theoretical curves corresponding to the different corrections are very similar to each other: this means that for the present experimental conditions, non-ideality of detectors is not so detrimental.…”

We present the characterization of a multi-pixel detector (SiPM, Hamamatsu) in the presence of dark-count and cross-talk effects. Our description yields a self-consistent calibration of the device, based on the light under investigation, which is used to evaluate shot-by-shot detected-photon numbers including dark-counts and cross-talk. The analysis allows us to reliably reconstruct the detected-photons statistics of different light states by taking into account the modifications introduced by detector features. Finally we quantify photon-number correlations in bipartite states and use the data to produce conditional states: only if dark-count and cross-talk effects can be neglected, the experimental results match theory.
