Jitter modulation by photon wavelength variation in single-photon avalanche diodes (SPADs)

Optical and Quantum Electronics, 2021
In 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,

Active-Quenching and Gating Circuits for Single-Photon Avalanche Diodes (SPADs)

IEEE Transactions on Nuclear Science, 1982
Single-photon detection by avalanche photodiodes with uniform breakdown over the junction area (single--photon avalanche diodes SPADs) is well known. The active quenching method, introduced by the authors, has been shown to avoid drawbacks of passive-quenching circuits and provide accurate operation of the devices.

An Estimation of Single Photon Avalanche Diode (SPAD) Photon Detection Efficiency (PDE) Nonuniformity

IEEE Sensors Journal, 2013
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, 2007
In 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 ...
