Single-photon detectors (SPDs) are the most sensitive instruments for light detection. In the
near-infrared range, SPDs based on III–V compound semiconductor avalanche photodiodes …

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

Depth and intensity profiling of targets at a range of up to 10 km is demonstrated using time-
of-flight time-correlated single-photon counting technique. The system comprised a pulsed …

This paper highlights a significant advance in time-of-flight depth imaging: by using a
scanning transceiver which incorporated a free-running, low noise superconducting …

We have used an InGaAs/InP single-photon avalanche diode detector module in
conjunction with a time-of-flight depth imager operating at a wavelength of 1550 nm, to …

We present a fully integrated InGaAs/InP negative feedback avalanche diode (NFAD) based
free-running single-photon detector (SPD) designed for accurate lidar applications. A free …

We demonstrate a high-speed photon-counting laser ranging system with laser pulses of
multiple repetition rates to extend the unambiguous range. In the experiment, the laser …

We report room temperature operation of telecom wavelength single-photon detectors for
high bit rate quantum key distribution (QKD). Room temperature operation is achieved using …

Photon-counting laser ranging has attracted a lot of research interest for its application in the
altimeter. In this letter, we report a large scale multi-beam photon-counting laser imaging …

In this paper, high-speed surface-illuminated Ge-on-Si pin photodiodes with improved
efficiency are demonstrated. With photon-trapping microhole features, the external quantum …
