Optoelectronic microprocessors built using existing chip manufacturing

High-performance prototype means chipmakers could now start building optoelectronic chips.
Using only processes found in existing microchip fabrication facilities, researchers at MIT, the University of California at Berkeley, and the University of Colorado have produced a working optoelectronic microprocessor, which computes electronically but uses light to move information.

Optical communication could dramatically reduce chips’ power consumption, which is not only desirable in its own right but essential to maintaining the steady increases in computing power that we’ve come to expect.
