Accurate model for single-photon avalanche diodes

IET Circuits, Devices & Systems, 2008
An accurate model useful for simulating single-photon avalanche diodes including biasing circuits is presented. The authors developed the model using Verilog-A codes to describe both static and dynamic behaviours. The derived model fits experimental results extracted from practical devices better than the one used in the open literature.

Single photon source characterization with a superconducting single photon detector [PDF]

, 2005
Superconducting single photon detectors (SSPD) based on nanopatterned niobium nitride wires offer single photon counting at fast rates, low jitter, and low dark counts, from visible wavelengths well into the infrared.

Analytical Evaluation of Signal-to-Noise Ratios for Avalanche- and Single-Photon Avalanche Diodes [PDF]

Sensors, 2021
Performance of systems for optical detection depends on the choice of the right detector for the right application. Designers of optical systems for ranging applications can choose from a variety of highly sensitive photodetectors, of which the two most prominent ones are linear mode avalanche photodiodes (LM-APDs or APDs) and Geiger-mode APDs or ...

Current-Assisted SPAD with Improved p-n Junction and Enhanced NIR Performance

Sensors, 2020
Single-photon avalanche diodes (SPADs) fabricated in conventional CMOS processes typically have limited near infra-red (NIR) sensitivity. This is the consequence of isolating the SPADs in a lowly-doped deep N-type well.

Quantum detector tomography of a time-multiplexed superconducting nanowire single-photon detector at telecom wavelengths [PDF]

, 2013
Superconducting nanowire single-photon detectors (SNSPDs) are widely used in telecom wavelength optical quantum information science applications. Quantum detector tomography allows the positive-operator-valued measure (POVM) of a single-photon detector ...

Optical OFDM With Single-Photon Avalanche Diode

IEEE Photonics Technology Letters, 2015
In this letter, an optical orthogonal frequency division multiplexing (OFDM) system based on a single-photon avalanche diode (SPAD) receiver is presented. SPAD detectors do not require a transimpedance amplifier as they operate in the Geiger mode. This poses challenges on detecting continuous data carrying signals. However, in this letter, we show that
