Gbps-Class Solar-Blind WDM Optical Wireless Communication By (264, 274, 282)-nm Deep-UV LEDs and CsTe Photomultiplier Tube

Abstract

A Gbps-class wavelength-division multiplexing transmission within the solar-blind band was demonstrated for the first time with (264, 274, 282)-nm AlGaN-based LEDs and a CsTe photomultiplier-tube over a 2-m weakly-collimated free-space link in standard indoor illumination.
