SPADA: single-photon avalanche diode arrays

IEEE Photonics Technology Letters, 2005
We present a silicon monolithic array of 60 photon counters (single-photon avalanche diode array) for two-dimensional imaging, with detection efficiency higher than 30% in the visible range. The fabricated solid-state array is rugged and easy to be integrated in the optical system.

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.

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 ...

Principles and features of single-photon avalanche diode arrays

Sensors and Actuators A: Physical, 2007
This is the first of two serial papers dealing on single-photon avalanche diode (SPAD) topics. Aim of the series is to discuss in depth the design and fabrication of our SPAD-A array system for two-dimensional single-photon imaging, able to count and time-tag single photons by means of a monolithic array sensor.

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 ...

Variable-Load Quenching Circuit for single-photon avalanche diodes

Optics Express, 2008
We present a compact 50 microm x 100 microm cell for single-photon detection, based on a new circuitry monolithically integrated together with a 20 microm-diameter CMOS Single-Photon Avalanche Diode (SPAD). The detector quenching relies on a novel mechanism based on starving the avalanche current till quenching through a variable-load (VLQC, Variable ...
