Gb/s Optical Wireless Communications up to 17 meters using a UV-C Micro-Light-Emitting Diode

Abstract

We demonstrate Gb/s data rates up to distances of 17m using a single UV-C micro-light-emitting diode and Orthogonal Frequency Division Multiplexing modulation . To our knowledge, this is the longest reported range for Gb/s UV-C LED-based optical wireless communications.

Efficient White-Light Visible Light Communication With Novel Optical Antennas Based on Luminescent Solar Concentrators

“…Several recent studies have been carried out embedding fast LED sources and receivers, reporting very high data rates ranging from several hundred Mbps to Gbps [14]- [16]. However, the majority of these pioneering studies were typically carried out in a laboratory setting [17], [18], exploiting small-sized, fast LEDs as a source, or even on micro LEDs [19], achieving relatively short communication links in a very protected environment. This approach is hardly suitable for the implementation of realistic VLC links or Li-Fi architecture [20], the latter aiming at the exploitation of ordinary high-power white LEDs (WLEDs) as illumination and communication sources.…”
