This letter presents a novel technique to achieve high-speed visible light communication (VLC) using white light generated by a blue GaN μLED and a yellow fluorescent copolymer. We generated white light suitable for room illumination by optimizing the ratio between the blue electroluminescence of the μLED and yellow photoluminescence of the copolymer color converter. Taking advantage of the components’ high bandwidth, we demonstrated 1.68 Gb/s at a distance of 3 cm (at 240 lx illumination). To the best of our knowledge, this is the fastest white light VLC results using a single blue LED/color converter combination.
