PHOTON COUNTING MODULE BASED ON AVALANCHE PHOTODIODES

Photon counting techniques with silicon avalanche photodiodes.

The properties of avalanche photodiodes and associated electronics required for photon counting in the Geiger and the sub-Geiger modes are reviewed. When the Geiger mode is used, there are significant improvements reported in overall photon detection efficiencies (approaching 70% at 633 nm), and a timing jitter (under 200 ps) is achieved with passive quenching at high overvoltages (20-30 V). Th...

III-Nitride photon counting avalanche photodiodes

In order for solar and visible blind III-nitride based photodetectors to effectively compete with the detective performance of PMT there is a need to develop photodetectors that take advantage of low noise avalanche gain. Furthermore, in certain applications, it is desirable to obtain UV photon counting performance. In this paper, we review the characteristics of III-nitride visible-blind avala...

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 ...

SINGLE-PHOTON DETECTOR MODULE APPLICATION NOTE Single-photon detection with InGaAs/InP avalanche photodiodes

When most people think of detecting single-photons, photomultiplier tubes probably spring to their mind. Indeed, for a long time these were the detectors of choice in ultrasensitive detection and spectroscopy. Today, however other types of detectors allow to reach a single-photon sensitivity. Special semiconductor devices called singlephoton avalanche diodes (SPAD) have been developed, optimise...
