English abstract:
Recently, a fully integrated optical fiber
receiver was reported based on single-photon avalanche
diode detectors to reduce the sensitivity gap to the quantum
limit. This was realized through an array of four detectors
to overcome the parasitic effects dominated by afterpulsing
which prevent a single detector from providing an
acceptable performance to serve as an optical receiver.
However, the array structure imposes an extra effect called
"crosstalk," which needs to be accurately characterized.
Thanks to the memoryless nature of dark noise statistics,
we present an effective method to investigate the intrinsic
parasitic effects of the array based on an all-at-once dark
noisemeasurement. The corresponding detection probabilities
and delays versus excess bias voltage are obtained
for different parasitics at all detectors. The results are
used to model crosstalk and estimate the error probabilities
required for bit error ratio analysis and structure
optimization. The accuracy of the estimations is verified by
experimental data.

Keywords:
Afterpulsing, crosstalk, dark count, detector dead time, optical receiver, single-photon avalanche diode (SPAD).
