Abstract
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.
