Firm beats Intel to 10Gbit CMOS photonics chip

A CALIFORNIA FIRM claimed that it has put a fibre optic interface directly onto a silicon chip. That means, according to Luxtera, that one day we'll have CPUs with optical buses shuffling huge amounts of data in and out of the heap.

Luxtera claimed its CMOS Photonics technology can provide the 10Gbit/sec optical modulation needed for high speed optical fibre communications.

Gabriele Sartori, VP of marketing at Luxtera, and who regular INQ readers will recall used to be AMD's "Mr Hypertransport", claimed his firm is the only one to produce a product at 10Gbit/sec, and to make it in normal silicon.

Intel has demonstrated similar products but has given no date for releasing chips with similar properties.

CEO Alex Dickinson said that Luxtera chips are built using the same CMOS process that its development partner - Freescale Semi - uses for its microprocessors.

He said that the integration of 10G photonics into normal silicon processes was "a highly disruptive event" for both the semi and optics industries.

The integration of optical interfaces into VLSI chips "will dramatically reduce the cost of high speed links," he said.
