Small Size Improves DUV LED Efficiency

USTC team shows how smaller chip size can deliver higher AlGaN-based DUV LED light output power density and peak external quantum efficiency Deep ultraviolet (DUV) light source have numerous valuable applications, including germicidal irradiation, phototherapy, water/air/food sterilization, and optical communication. But while research on AlGaN-based DUV LEDs has made exciting progress, their industrial applications are still in their infancy. This is because of their limited wall plug efficiency (WPE) which is cause by low external quantum efficiency (E...

Japan Researchers Use DUV LED to Achieve High Speed LiFi Transmission

A new study published by researchers at Tohoku University in Japan introduced a novel solution for realizing high speed light transmission via deep UV (DUV) LEDs. The results were published in Applied Physics Letters on July 22, 2020. The research team highlighted two major issues of using LEDs as light source for wireless communication. One thing is that faster modulation requires smaller device size but smaller LEDs usually lack power. Another issue is that both visible and infrared optical wireless communications can have significant solar interference. To av...
