We demonstrate the use of deep ultraviolet (DUV) micro-LEDs for long-distance line-of-sight optical wireless communications. With a single 285nm-emitting micro-LED, we have respectively achieved data rates greater than 6.5 Gb/s at a distance of 10m and 4 Gb/s at 60m. Moreover, we obtained >1Gb/s data rates at a distance of 116 m. To our knowledge, these results are the highest data rates at such distances thus far reported using deep DUV micro-LEDs and the first demonstration of Gb/s communication at >100m using any micro-LED-based transmitter
