    Intel’s Justin Rattner on New Laser Chip Business

    . . . .
    It’s a 100-gigabit-per-second transceiver [a device that sends data between computers along an optical fiber]. We use conventional CMOS [chip] fabrication techniques to actually build the lasers into the chip. We showed a 50-gigabit-per-second link a few years ago that was built in the lab (see “Computing at the Speed of Light”); the current chip can do 100 gigabits per second, but the connector, which we teamed up with Corning to build, has the ability to go to 1.6 terabits per second.

    In the data center—[meaning] more bandwidth at much lower cost, and what looks like a big win on the energy-efficiency side. The data center guys love all this capacity but with cables that are teeny-tiny. Right now most data centers are running at 10 gigabits per second; a few people have deployed 40 gigabits per second. People at Facebook [have] begun to think about other applications for silicon photonics [inside server] racks.
