Characterization of InGaAs/InP single-photon avalanche diodes

2010 IEEE Photinic Society's 23rd Annual Meeting, 2010
Improvements on InGaAs/InP Single Photon Avalanche Diodes (SPADs) make them very promising for many NIR single-photon counting applications. In order to fully exploit such detectors, it is mandatory to operate them in optimized working conditions and in association with proper front-end electronics.

Photon Counting Heterodyne With a Single Photon Avalanche Diode

IEEE Photonics Technology Letters, 2021
To implement high sensitivity, good anti-interference and low data rate simultaneously in optical heterodyne system, a photon counting heterodyne mechanism is proposed in this letter. Due to the stochastic behavior, a single photon avalanche diode (SPAD) is used as both a photon collector and a sparse sampler.

Limits to the Timing Performance of Single Photon Avalanche Diodes

1995
Semiconductors p-n junctions with uniform breakdown voltage are gaining acceptance as single-photon detectors in the visible and near infrared wavelength range in many applications, such as measurements of fast optical signals, laser ranging, Optical TimeDomain Reflectometry and in all cases where fast andlor weak optical signals must be detected1,2 ...

Silicon single photon avalanche diodes: situation and prospect

SPIE Proceedings, 2007
Photon counting was introduced and developed during four decades relying on Photomultiplier Tubes (PMT), but interesting alternatives are nowadays provided by solid-state single-photon microdetectors. In particular, Silicon Single-Photon Avalanche-Diodes (SPAD) attain remarkable basic performance, such as high photon detection efficiency over a broad ...

Single photon avalanches diodes

Photoniques
Twenty years ago the detection of single photons was little more than a scientific curiosity reserved to a few specialists. Today it is a flourishing field with an ecosystem that extends from university laboratories to large semiconductor manufacturers.

Physics and numerical simulation of single photon avalanche diodes

IEEE Transactions on Electron Devices, 1997
We present results of the numerical simulation of the transient behavior of shallow junction single photon avalanche diodes (SPAD's). We developed a bidimensional model for above breakdown simulations and show that the initially photogenerated charge density builds up locally by an avalanche multiplication process and then spreads over the entire ...

Improving the performance of silicon single-photon avalanche diodes

SPIE Proceedings, 2011
Many applications require high performance Single Photon Avalanche Diodes (SPAD) either as single pixels or as small arrays of detectors. Although currently available silicon devices reached remarkable performance, nevertheless further improvements are needed in order to meet the requirements of most demanding time-resolved techniques. In this paper we

Single photon avalanche diode for single molecule detection

Review of Scientific Instruments, 1993
A commercially available single photon avalanche photodiode in a passively quenched circuit is used with time-correlated single photon counting modules to achieve subnanosecond time response together with high quantum efficiency and low dark noise. These characteristics are required for experiments in single molecule detection and spectroscopy in which

Single photon avalanche diode for single molecule detection

Optical Society of America Annual Meeting, 1992
Single dye molecules may be detected as they pass through a 0.4 pL sample volume by using repetitively pulsed laser excitation and time-gated single photon counting to detect the weak single-molecule fluorescence and simultaneously discriminate promptly scattered Raman photons arising from the >1013 solvent molecules.1 Previous experiments have ...
