This letter presents a novel technique to achieve high-speed visible light communication (VLC) using white light generated by a blue GaN (mu ) LED and a yellow fluorescent copolymer. We generated white light suitable for room illumination by optimizing the ratio between the blue electroluminescence of the (mu ) LED 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.
