University researchers set world record for fast, efficient data center LED

University of Illinois and Notre Dame researchers set LED switching speed record

1 Oct 31 · 12d ago · 4 articles · 1 source · development 1 of 2

A collaboration between the University of Illinois Urbana-Champaign's Grainger College of Engineering and Notre Dame achieved a world record for optical switching speed in quantum well LEDs, with a gallium nitride micro-LED device operating at 2.75 gigahertz optical modulation bandwidth while consuming 25 milliwatts of power. The findings were published in IEEE Electron Device Letters.

“Ninety percent of communications in data centers is short range, meaning less than 10 meters. If we want to manage energy use in data centers, we need to consider lower-power optical communications such as LEDs.”
