Comparative study of afterpulsing behavior and models in single photon counting avalanche photo diode detectors

Avalanche Photodiodes As Single Photon Detectors

A 130nm CMOS Single Photon Avalanche Diode

We report on the first implementation of a single photon avalanche diode (SPAD) in 130nm CMOS technology. The SPAD is fabricated as p+/nwell junction with octagonal shape. A guard ring of p-well around the p+ anode is used to prevent premature discharge. To investigate the dynamics of the new device, both active and passive quenching methods have been used. Single photon detection is achieved b...

Actively quenched single-photon avalanche diode for high repetition rate time-gated photon counting

This paper reports an experimental characterization of the EG&G SPCM-AQ single-photon avalanche diode module with an active quenching bias circuit that gives a dead time of ;35 ns for use in high count rate, fast timing applications. A quantum efficiency of .70% and an optimal timing jitter with a full width at one-thousandth maximum of 1.5 ns is obtained if the light is tightly focused to a sp...

Scintillation induced response in passively-quenched Si-based single photon counting avalanche diode arrays.

An optical electrical model which studies the response of Si-based single photon counting arrays, specifically silicon photomultipliers (SiPMs), to scintillation light has been developed and validated with analytically derived and experimental data. The scintillator-photodetector response in terms of relative pulse height, 10%-90% rise/decay times to light stimuli of different rise times (rangi...

Single Photon Avalanche Photodiodes for Near-Infrared Photon Counting

InP-based single photon avalanche diodes (SPADs) have proven to be the most practical solution currently available for many applications requiring high-performance photon counting at near-infrared wavelengths between 1.0 and 1.6 μm. We describe recent progress in the design, characterization, and modeling of InP-based SPADs, particularly with respect to the dark count rate vs. photon detection ...
