High speed single photon detection in the near infrared
Open accessAbstract
InGaAs avalanche photodiodes (APDs) are convenient for single photon detection in the near infrared (NIR) including the fiber communication bands (1.31∕1.55μm). However, to suppress afterpulse noise due to trapped avalanche charge, they must be gated with megahertz repetition frequencies, thereby severely limiting the count rate in NIR applications. Here, the authors show gating frequencies for InGaAs APDs well beyond 1GHz. Using a self-differencing technique to sense much weaker avalanches, the authors reduce drastically afterpulse noise. At 1.25GHz, they obtain a detection efficiency of 10.8% with an afterpulse probability of 6.16%. In addition, the detector features low jitter (55ps) and a count rate of 100MHz.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
