Abstract

This letter presents a visible light communication (VLC) system based on a single 50-µm gallium nitride light emitting diode (LED). A device of this size exhibits a 3-dB modulation bandwidth of at least 60 MHz—significantly higher than commercially available white lighting LEDs. Orthogonal frequency division multiplexing is employed as a modulation scheme. This enables the limited modulation bandwidth of the device to be fully used. Pre- and postequalization techniques, as well as adaptive data loading, are successfully applied to achieve a demonstration of wireless communication at speeds exceeding 3 Gb/s. To date, this is the fastest wireless VLC system using a single LED. Index

N1 - This paper demonstrates record performance in high-speed modulation of gallium nitride LEDs for advanced visible light based Datacom applications. Visible light communications is a field of considerable current international interest, based on the vision of ‘LiFi’ (light fidelity) as a new networked, bi-directional communications infrastructure to complement and supplement WiFi. The bespoke devices concerned were developed at Strathclyde under an EPSRC Programme Grant conceived and led by Professor Dawson, which is currently setting international benchmarks in the field. The paper has been cited 133 times to date (Google Scholar).
