A single-photon-avalanche-diode 3d imager

Proceedings of the 31st European Solid-State Circuits Conference, 2005. ESSCIRC 2005., 2005
This paper describes the design and characterization of a 64-pixel array exploiting the high sensitivity offered by single photon avalanche diodes, fabricated in a conventional high-voltage 0.8/spl mu/m CMOS technology, and aimed at three dimensional measurements using the time-of-flight technique.

Modeling of afterpulsing in single-photon avalanche diodes

SPIE Proceedings, 2011
The afterpulsing noise in Single-Photon Avalanche Diodes (SPADs) is modeled and investigated in order to evaluate its impact on SPAD performance, in terms of maximum count rate, signal-to-noise ratio, etc. From measurements fitting, we identified three/four types of defects that we then used to simulate the behavior of the SPAD when operated in ...

Single Photon Avalanche Diodes for space applications

2011 IEEE Nuclear Science Symposium Conference Record, 2011
We study the possibility to use Single Photon Avalanche Diodes (SPADs) optically coupled to scintillating fibers as a novel type of gamma-ray detector for space applications. SPADs are silicon devices operating under polarization conditions above the junction breakdown voltage (typical overvoltage of 5V), for which a single photon interacting in the ...

Integrated simulator for single photon avalanche diodes

2011 Numerical Simulation of Optoelectronic Devices, 2011
We present a new mono-dimensional device simulator optimized for the behavioral inspection and design of single-photon avalanche diodes (SPAD). The particular operating conditions in which these pn junctions are used, reverse biased above the breakdown voltage, lead to a non-univocal I-V characteristic and a non-stationary behavior, which is difficult ...

Single-Photon Avalanche Diode for Scalable Particle Detection

IEEE EUROCON 2023 - 20th International Conference on Smart Technologies, 2023
Single-photon avalanche diodes (SPADs), also referred to as Geiger-mode avalanche photodiodes, are primarily utilized in photon detection and counting. In this work, we present a measurement of the time-of-flight of minimum ionizing particles with outstanding timing resolution, achieved by using SPADs as direct particle detectors.

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.

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 ...
