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

Scintillating fibers readout by Single Photon Avalanche Diodes (SPAD) for space applications
SPIE Proceedings, 2012We present the design and performances of a radiation detector based on plastic scintillating fibers with doubleside readout by means of large-area Single Photon Avalanche Diodes (SPAD). This can be the basic step toward the realization of a large-area, cost-effective position sensitive detector to be employed in future space gammaray observatories ...

Monolithic Single-Photon Avalanche Diodes: SPADs
2011The art of creating monolithic single-photon photodetectors is a mix of design skills and device physics knowledge, and it requires an understanding of the mechanisms underlying single-photon detection in highly complex integrated systems. This chapter begins with the fundamentals of avalanching, the basics for integration of avalanche photodiodes ...

Active-Quenching and Gating Circuits for Single-Photon Avalanche Diodes (SPADs)
IEEE Transactions on Nuclear Science, 1982Single-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.

2021 Symposium on VLSI Circuits, 2021
For the first time, heterogeneous integration of InGaAs/InAlAs single-photon avalanche diodes (SPADs) with Si photonics was realized and demonstrated through a low temperature die-to-die bonding technique. Together with the adoption of a triple-mesa structure in SPADs which not only avoids the surface exposure to the high electric field but also ...

Single photon avalanche diode (SPAD) is a temperature sensitive device. Even a slight variation of temperature can cause unstable performance in quantum efficiency, responsitivity and dark counts. Due to these reasons, unstable temperature could cause overall poor performance of SPAD.
