Solar-Blind Optical Wireless Communications Over 80 Meters Using a 265-nm High-Power Single-Chip DUV-LED Over 500 mW in Sunlight

Direct eye-pattern measurements based on a deep-ultraviolet (DUV) light emitting diode (LED) optical wireless communication system were performed in sunlight. A state-of-the-art, high-power DUV-LED was developed and used as transmitter consisting of only one LED chip with output power greater than 500 mW at its peak emission wavelength 265 nm. DUV receiver also that excluded sunlight high performance. We demonstrated clear eye-patterns 1 Mbps both line-of-sight (LOS) non-line-of-sight (NLOS) configurations over distance 80 meters
