Efficient photon number detection with silicon avalanche photodiodes
, 2010 We demonstrate an efficient photon number detector for visible wavelengths using a silicon avalanche photodiode. Under subnanosecond gating, the device is able to resolve up to four photons in an incident optical pulse. The detection efficiency at 600 nm

SiPM used as fast Photon-Counting Module and for Multiphoton Detection
, 2007 We demonstrate fast counting and multiphoton detection abilities of a Silicon Photo Multiplier (SiPM). In fast counting mode we are able to detect two consecutive photons separated by only 2.3 ns corresponding to 430 MHz.

A Gbps Building-to-Building VLC Link Using Standard CMOS Avalanche Photodiodes
IEEE Photonics Journal, 2017 A building-to-building free-space visible-light-communication link over more than 72 m link distance is presented. The link employs a dual data/clock optical channel from two 680-nm vertical-cavity surface-emitting laser laser-diodes.

High speed single photon detection in the near-infrared
, 2007 InGaAs avalanche photodiodes (APDs) are convenient for single photon detection in the near-infrared (NIR) including the fibre communication bands (1.31/1.55 $\mu$m).

Avoiding the Detector Blinding Attack on Quantum Cryptography
, 2010 We show the detector blinding attack by Lydersen et al [1] will be ineffective on most single photon avalanche photodiodes (APDs) and certainly ineffective on any detectors that are operated correctly.
