Single-Photon Avalanche Diodes (SPAD) are affordable photodetectors, capable to collect
extremely fast low-energy events, due to their single-photon sensibility. This makes them …

In this paper we present a photon number resolving detector at infrared wavelengths,
operating at room temperature and with a large dynamic range. It is based on the up …

A 16× 256 element single-photon avalanche diode array with a 256-channel, 3-bit on-chip
time-to-digital converter (TDC) has been developed for fluorescence-suppressed Raman …

The art of creating monolithic single-photon photodetectors is a mix of design skills and
device physics knowledge, and it requires an understanding of the mechanisms underlying …

We demonstrated a robust spike cancellation by virtue of optical balancing technique for the
near-infrared single-photon detection based on InGaAs/InP avalanche photodiode. A 31 dB …

Time-of-flight sensing with single-photon sensitivity enables new approaches for the
localization of objects outside a sensor's field of view by analyzing backscattered photons. In …

We report benchmark tests of a new single-photon counting detector based on a GaAsP
photocathode and an electron-bombarded avalanche photodiode developed by …

Avalanche-photodiode-based near-infrared single-photon detectors have seen rapid
development in the last two decades because of their enormous internal gain, high …

InGaAs/InP-based semiconductor avalanche photodiodes are usually employed for single-
photon counting at telecom wavelength. However they are affected by afterpulsing which …

We demonstrate the feasibility of time-resolved diffuse reflectance measurements at small
source-detector separations using a single-photon avalanche diode operated in time-gated …
