Researchers Announce World's Fastest Light Emitters

A young Kelabit scientist has co-invented the world's fastest spontaneous Light Emitting Transistor (LET) and Light Emitting Diode (LED). Gabriel Walter, 32, an electrical engineering doctor from the University of Illinois-Urbana Champaign (UIUC), scored both a national and personal breakthrough in technology by co-inventing light emitters capable of transmitting at speeds of up to 7GHz. For more than 40 years, the scientific community believed that efficient spontaneous light device cannot be operated at bandwidths larger than 1 GHz.
