Scientific Reports, 2021 Conventional two-photon microscopes use photomultiplier tubes, which enable high sensitivity but can detect relatively few photons per second, forcing longer pixel integration times and limiting maximum imaging rates.

Simulation of Silicon Photomultipliers [PDF]
Proceedings of International Workshop on New Photon-detectors — PoS(PhotoDet 2012), 2013 We present a software framework for the simulation of Silicon Photomultipliers (SiPM). The simulation provides a detailed model of the SiPM response to arbitrary light pulses, depending on the basic SiPM characteristics which have to be determined by measurements.

Self-heating effect in Silicon-Photomultipliers
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2022 The main effect of radiation damage in a Silicon-Photolumtiplier (SiPM) is a dramatic increase in the dark current. The power dissipated, if not properly cooled, heats the SiPM, whose performance parameters depend on temperature. Heating studies were performed with a KETEK SiPM, glued on an Al$_2$O$_3$ substrate, which is either directly connected to ...

Back-Side Readout Silicon Photomultiplier. [PDF]
IEEE Trans Electron Devices, 2012 We present a novel structure for the back-side readout silicon photomultipler (SiPM). Current SiPMs are front-illuminated structures with front-side readout, which have relatively small geometric fill factor leading to degradation in their photon detection efficiency (PDE). Back-side readout devices will provide an advantageous solution to achieve high

Performance Estimation and Selection Guideline of SiPM Chip within SiPM-Based OFDM-OWC System
Photonics, 2022 The orthogonal frequency division multiplexing (OFDM), which has high spectral efficiency, is an attractive solution for silicon photomultiplier (SiPM)-based optical wireless communication (OWC) systems to boost data rates.

Photon-number statistics with silicon photomultipliers [PDF]
Journal of the Optical Society of America B, 2010 We present a description of the operation of a multi-pixel detector in the presence of non-negligible dark-count and cross-talk effects. We apply the model to devise self-consistent calibration strategies to be performed on the very light under investigation.
