The transistor laser invented by scientists at the University of Illinois at Urbana-Champaign has now been found to possess fundamental non-linear characteristics that are new to a transistor and permit its use as a dual-input, dual-output, high-frequency signal processor. "We have hit upon something surprisingly fundamental and rich in possibilities," said Nick Holonyak Jr., a John Bardeen Chair Professor of Electrical and Computer Engineering and Physics at Illinois. "We have, at once, a new form of transistor and a new form of laser."
By modifying the base region with quantum wells and resonator configurations, Holonyak, electrical and computer engineering ...
