Far-UVC LEDs transmit data at record speed | Ferdinand-Braun-Institut

Researchers at Ferdinand-Braun-Institut (FBH), the University of Strathclyde, and the University of Cambridge demonstrated wireless optical communication using far-UVC LEDs at wavelengths below 235 nm, achieving data rates up to 1.5 gigabits per second over a 30 cm line-of-sight link. The FBH-developed LEDs are optimized for high optical power and fast modulation by segmenting the emitting surface to reduce capacitance and increase current density. Far-UVC offers low solar background outdoors and stronger Rayleigh scattering for potential non-line-of-sight links. Next steps include testing longer distances, non-line-of-sight performance, and environmental effects on transmission.
