Eye and Skin-Safe 150 Mbps Optical Wireless Communications Over 1 m Using UVC LEDs
We demonstrate an eye and skin-safe optical wireless communication link, at a transmission distance of 1 m, using ultraviolet-C (UVC) light-emitting diodes (LEDs) emitting at 235 and 255 nm, with error-free data rates up to 150 Mbps. Irradiance levels at the receiver were maintained within eye and skin-safe exposure limits. Operating at these short wavelengths confers an improvement in received peak signal-to-noise ratio (SNR) compared to previous demonstrations around 270-280 nm, thanks to the higher permitted exposure limits at shorter UVC wavelengths.
