Analytical Evaluation of Signal-to-Noise Ratios for Avalanche- and Single-Photon Avalanche Diodes [PDF]

open access: yesSensors, 2021
Performance of systems for optical detection depends on the choice of the right detector for the right application. Designers of optical systems for ranging applications can choose from a variety of highly sensitive photodetectors, of which the two most prominent ones are linear mode avalanche photodiodes (LM-APDs or APDs) and Geiger-mode APDs or ...

Design Criteria for InGaAs/InP Single-Photon Avalanche Diode

open access: yesIEEE Photonics Journal, 2013
We provide a detailed insight on the design of InGaAs/InP single-photon avalanche diode (SPAD) for 1.55- μm photon detection. In order to lower SPAD noise [the dark count rate (DCR)] without lowering photon detection efficiency (PDE) or increasing

Neural Imaging Using Single-Photon Avalanche Diodes [PDF]

open access: yesBasic and Clinical Neuroscience Journal, 2017
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 minimum dark 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.The
