High-speed visible light Communication system based on SiPM

Abstract:

Silicon Photomultiplier (SiPM) is a photodetector with very high sensitivity, fast response and good performance in oversaturation conditions. When SiPM faces incident optical radiation (sometimes imperceptible for other photodetectors) is able to detect very small variations of light. In this work, we present a SiPM-based optical receiver ables to discriminate small light signals from background noise, while exposed to ambient light conditions without optical filters or another additional optical device. Such device is the core of a new high-speed Visible Light Communication (VLC) system with multiuser capability. This prototype is an innovation in the communications industry, built with technology originally developed for particle physics experiments, a groundbreaking connection between science and industry.
