Intel Labs’ “silicon photonics” venture is developing a 100-gigabit-per-second transceiver [a device that sends data between computers along an optical fiber], says former Intel CTO Justin Rattner in an interview with MIT Technology Review.

It is targeted to the data center — [meaning] more bandwidth at much lower cost, and what looks like a big win on the energy-efficiency side.

Regarding Moore’s law, “we can see ahead two, maybe three, generations and we feel pretty good about that, but beyond that it starts to get a little fuzzy,” he said. “Gallium arsenide transistors on a silicon substrate are a possibility to pursue.” [...]
