Abstract

An InGaN micro-LED (μLED) array acting as photodetector receivers (referred as μLED-based PDs) was first proposed and experimentally demonstrated for high-speed parallel visible light communication (VLC) using 405 nm violet laser diodes (LDs) as transmitters. We studied the optoelectronic characteristics of the μLEDs-based PDs with various diameters of 100 μm, 60 μm and 40 μm and the parallel communication characteristics using the μLED-based PD array. With on-off keying (OOK) modulation scheme, the corresponding maximum data rates of 180 Mbps, 175 Mbps and 185 Mbps at a distance of about 1 m were obtained with BERs of 3.5 × 10^-3, 3.7 × 10^-3 and 3.5 × 10^-3, respectively.
