Afterpulsing studies of low noise InGaAs/InP single-photon negative feedback avalanche diodes
Boris Korzh, Tommaso Lunghi, Kateryna Kuzmenko +2
We characterize the temporal evolution of the afterpulse probability in a free-running negative feedback avalanche diode (NFAD) over an extended range, from 300 ns to 1…
Absolute calibration of fiber-coupled single-photon detector
Tommaso Lunghi, Boris Korzh, Bruno Sanguinetti +1
We show a setup for characterising the efficiency of a single-photon-detector absolutely and with a precision better of 1%. Since the setup does not rely on calibrated devices and…
Advantages of gated silicon single photon detectors
T. Lunghi, E. Pomarico, C. Barreiro +3
We present a gated silicon single photon detector based on a commercially available avalanche photodiode. Our detector achieves a photon detection efficiency of 45\pm5% at 808 nm w…
Free Running Single Photon Detection based on a negative feedback InGaAs APD
Tommaso Lunghi, Claudio Barreiro, Olivier Guinnard +4
InGaAs/InP-based semiconductor avalanche photodiode are usually employed for single-photon counting at telecom wavelength. However they are affected by afterpulsing which limits th…
