Abstract

Gallium-nitride (GaN) based light-emitting diodes (LEDs) are highly-efficient sources for general purpose illumination. Furthermore, being semiconductor-based light sources, they are readily compatible with intelligent drive electronics. Visible light communications (VLC) is a technology which leverages these advantageous properties of GaN LEDs and can supplement existing wireless communications by offering a large, licence-free spectral bandwidth. Here we report on progress in the development of micro-scale GaN LEDs (micro-LEDs), optimised for VLC. These blue-emitting micro-LEDs are shown to have very high electrical-to-optical modulation bandwidths, exceeding 800~MHz. The data transmission capabilities of the micro-LEDs are illustrated by demonstrations using on-off-keying (OOK), pulse-amplitude modulation (PAM) and orthogonal frequency division multiplexing (OFDM) modulation schemes to transmit data over free space at rates of 1.7, 3.4 and 5 Gb/s, respectively.
