Non-Markovian Property of Afterpulsing Effect in Single-Photon Avalanche Detector

Neural Imaging Using Single-Photon Avalanche Diodes

Introduction: This paper analyses the ability of single-photon avalanche diodes (SPADs) for neural imaging. The current trend in the production of SPADs moves toward the minimumdark count rate (DCR) and maximum photon detection probability (PDP). Moreover, the jitter response which is the main measurement characteristic for the timing uncertainty is progressing. Methods: The neural imaging pro...

Experimental multi-photon-resolving detector using a single avalanche photodiode

There is an increasing need for identifying the number of photons that is contained within a weak light pulse or time interval of a weak cw light field. A device capable of photon-number resolution would contribute both to fundamental research in the area of quantum optics and to more-or-less practical quantum communication systems, such as quantum key distribution schemes [1]. In the former ca...

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...

Memory effect in silicon time-gated single-photon avalanche diodes

Single photon quantum filtering using non-Markovian embeddings.

We determine quantum master and filter equations for continuous measurement of systems coupled to input fields in certain non-classical continuous-mode states, specifically single photon states. The quantum filters are shown to be derivable from an embedding into a larger non-Markovian system, and are given by a system of coupled stochastic differential equations.
