A Large Field-of-view (FOV) Visible Laser Light Communication System Reaching 180° with Silicon Photomultiplier Receiver

As a compelling part of the next-generation wireless communication technologies, visible light communication (VLC) enables the use of light bulbs as transmitters while addressing the shortage of spectrum resources. To achieve both lighting and communication applications, a large field of view (FoV) is desirable. Laser-based VLC technology has attracted increasing attention due to its high data rate but visible laser light communication (VLLC) system with a large FoV has yet been well studied. In this work, we design a VLLC system using a white laser transmitter and a silicon photomultiplier (SiPM) receiver with ultra-wide FoV reaching 180°. The preliminary experimental results show that the system enables transmission data rates over 500Mbps. This work suggests that the demonstrated VLLC system is promising for wide-coverage LiFi applications.
