Selecting Single Photon Avalanche Diode (SPAD) Passive-Quenching Resistance: An Approach
IEEE Sensors Journal, 2013An approach useful for designing the passive quenching circuitry of single-photon avalanche diodes (SPADs) is presented. A method is introduced which enables a chip designer to correctly select the appropriate resistance of the passive quenching component of the chip.

An analytical expression estimating the photon detection efficiency (PDE) nonuniformity of single-photon avalanche diodes is derived. The estimation relies upon well-established semiempirical and analytical models and is useful for medium- to high-resolution arrays, as well as for wafer-to-wafer variations.

The new generation of SPAD--Single-Photon Avalanche Diodes arrays
Il Nuovo Cimento C, 2007In the last years the single-photon detection with silicon devices has become an important goal. Here we present the performance of a new generation of single-photon avalanche diodes manufactured by ST-Microelectronics. The 5 x 5 array configuration has been also realized and the performances, in terms of crosstalk and common readout mode, have been ...

Single photon avalanche diodes (SPADs) for 1.5 μm photon counting applications
Journal of Modern Optics, 2007The paper reports on the design and characterization of InGaAs/InP single photon avalanche diodes (SPADs) for photon counting applications at wavelengths near 1.5 µm. It is shown how lower internal electric field amplitudes can lead to reduced dark count rates, but at the expense of degraded afterpulsing behaviour and larger timing jitter.

Jitter modulation by photon wavelength variation in single-photon avalanche diodes (SPADs)
Optical and Quantum Electronics, 2021In this paper, jitter modulation of SPADs in different photon wavelengths is explored. It is shown that in p+/n-well, or p+/deep n-well SPADs the jitter increases with increasing the photon wavelength, due to an increase in avalanche buildup time (τ). The avalanche buildup time is enhanced in higher wavelength due to the deeper photon absorption depth,

Single photon avalanche diode (SPAD) VLC system and application to downhole monitoring
2014 IEEE Global Communications Conference, 2014In this paper, it is demonstrated for the first time that the problem of continuous downhole monitoring in the oil and gas industry is effectively addressed by the use of visible light communication (VLC). As a reliable, flexible and low-cost technique, VLC can fulfill a critical need of operators to maintain production efficiency and optimize gas well
