Stanford breakthrough heralds super-efficient light-based computers

Infrared light passes through silicon the way visible light passes through glass. That makes it theoretically possible to replace wires with silicon fibers. Why bother: to transmit lots more data while using lots less energy. But until now there had been no way to automate the design of these optical strands. ‘We used (our) algorithm to design a working optical circuit and made several copies in our lab,’ said lead researcher Jelena Vuckovic. —> Read More
