Reports on the construction of silicon circuits by Mario Paniccia, the director of phototonics technology laboratory at Intel Corporation, Santa Clara, Calif. Circuits that can quickly switch light have been limited to exotic semiconductors that are difficult and expensive to manufacture, making the components too costly for applications other than major fiber-optic networks. But in February an Intel team led by Mario Paniccia unveiled a modulator made from common silicon that can process one gigabit of data per second, 50 times faster than previous experimental devices. Paniccia has since used prototypes to send high-definition video data between two computers. Intel says the technology could lead to far faster connectors between servers in corporate data centers, between personal computers and servers, and eventually between chips inside PCs themselves. |
