Modeling of afterpulsing in single-photon avalanche diodes
SPIE Proceedings, 2011The 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, 2011We 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, 2007This 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, 2011We 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
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 ...

Characterization of InGaAs/InP single-photon avalanche diodes
2010 IEEE Photinic Society's 23rd Annual Meeting, 2010Improvements 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.
