Luxtera Inc., a developer of CMS photonics technology, announced this week it has demonstrated technology that multiplexes four 10 Gb/s wavelengths onto a single fiber on a production CMOS die, resulting in a single fiber 40 Gb/s link. The company said the advance "reduces cost for high-bandwidth interconnect over traditional parallel fiber technology and paves the way for 100 Gb/s Ethernet data center connectivity." Luxtera recently announced sampling of its single-wavelength 10 Gb/s silicon photonics transceiver technology, implemented in standard SOI (silicon-on-insulator) CMOS process with integrated indium phosphate laser light sources. By combining that technology with wavelength division multiplexing (WDM) capability, Luxtera said, it is the first photonics company to demonstrate a feasibility of applying Moore’s Law to fiber bandwidth scalability implemented in a low-cost commercial CMOS fabrication process. The 40 Gb/s WDM technology development was partially funded by DARPA as part of the Electronic and Photonic Integrated Circuits (EPIC) phase I program. Successful completion of this phase enables Luxtera to secure additional funding for subsequent EPIC program phases with the ultimate goal of delivering commercial-quality, high-bandwidth transceiver technology, it said. Luxtera’s technology integrates high-performance photonics and mainstream electrits Luxtera’s products are developed in a standard CMOS fabrication process, additional digital logic can be integrated into the same chip along with optical devices, further reducing size, power consumption and cost, it said. Luxtera said it is delivery prototypes to development partners and will launch a commercial transceiver product line based on the technology in 2007. Future applications will icnlude chip-to-chip and intrachip optical connectivity, it said. For more information, visit: www.luxtera.com
