Avalanche photodiodes and quenching circuits for single-photon detection
TL;DR: Avalanche photodiodes, which operate above the breakdown voltage in Geiger mode connected with avalanche-quenching circuits, can be used to detect single photons and are therefore called singlephoton avalanche diodes SPAD's.

TL;DR: By probing the fluorescence lifetime of the single flavin on a photon-by-photon basis, the variation of flavin-tyrosine distance over time is observed, suggesting the existence of multiple interconverting conformers related to the fluctuating catalytic reactivity.
Journal ArticleDOI
Evolution and prospects for single-photon avalanche diodes and quenching circuits
TL;DR: In this article, the evolution of solid-state avalanche detectors of single optical photons is discussed and issues for further progress are discussed, and the main technological issues that hamper the development of detectors with wide sensitive area and of array detectors with high filling factor are illustrated.
Journal ArticleDOI
Principles and features of Single Photon Avalanche Diode Arrays
TL;DR: In this paper, the design and fabrication of a single-photon avalanche diode (SPAD) array system for counting and time-tagging single photons by means of a monolithic array sensor is discussed.
Journal ArticleDOI
Progress in Silicon Single-Photon Avalanche Diodes
TL;DR: Silicon single-photon avalanche diodes (SPADs) are nowadays a solid-state alternative to photomultiplier tubes (PMTs) in single photon counting (SPC) and time-correlated singlephoton counting over the visible spectral range up to 1mum wavelength as discussed by the authors.
