Light on Silicon Better Than Copper?

Facebook Twitter LinkedIn Email Comments
DURHAM, N.C., Nov. 4, 2010 — By integrating microscopically small lasers with thin film-light guides on silicon, Duke University electrical engineers have demonstrated how optical signals could replace copper in a host of electronic products. The structures on silicon not only contain tiny light-emitting lasers, but connect these lasers to channels that accurately guide the light to its target, typically another nearby chip or component. This new approach could help engineers who, in their drive to create tinier and faster computers and devices, are studying light as the basis for the next generation information...Read full article
