Infinera Presents on First-Ever Terabit PIC at OFC

Coherent Detection of 10x100Gb/s Channels

Sunnyvale, CA – March 4, 2011 – Infinera (Nasdaq: INFN) will present the results of the world’s first 1 Terabit/second (Tb/s) photonic integrated circuit (PIC) at next week’s Optical Fiber Conference. The 1 Tb/s PIC represents another step forward in the evolution of PIC technology to higher levels of integration and higher data rates.

The talk, by Dr. Radhakrishnan Nagarajan, Infinera research fellow and member of the PIC development team, will describe the structure and performance of a 1 Tb/s PIC receiver. The receiver receives and decodes ten channels of 100Gb/s each, using the QPSK modulation format and coherent detection. The receiver integrates more than 150 optical devices on a single monolithic Indium Phosphide chip.

“With PICs, Infinera has applied the manufacturing techniques of the Silicon industry to optics, and we expect we will be able to ride a long-term curve of more integration, greater functionality, higher data rates, and improved reliability, at the component level, system level, and network level,” said Dr. Nagarajan.

Terabits and Superchannels With Internet traffic growing at exponential rates, driven by video, cloud computing, and mobility, PIC technology will be required to support the growth of network capacity to accommodate this traffic, while reducing the per-bit cost, space, and power consumption, to enable service providers to carry the traffic while maintaining profitable business models. Photonic integration enables greater network reliability because connections between optical components are printed directly onto a chip. From a network architecture point of view, Terabit PICs could enable the use of “superchannels” or groups of data channels bonded together to enable more efficient use of network resources and the optical spectrum. At the consumer level, a 1 Tb/s PIC could enable the download of one high-definition movie file in a fifth of a second, or support the transmission of two million simultaneous videoconferences—all from a single pair of chips.

In 2004, Infinera began shipping optical systems based on 100Gb/s PICs. In less than two years, Infinera systems seized first place in the North American long-haul optical networking market, according to data from independent analysts the Dell’Oro Group. Earlier this week, in partnership with pan-European service provider Interoute, Infinera announced the results of the latest field trial of its next generation of commercial PICs, which deliver 500Gb/s of capacity on a single pair of chips. Optical systems based on the 500Gb/s PICs are planned for commercial availability next year. The 1 Tb/s PIC represents another leap forward in the evolution of photonic integration.

Dr. Nagarajan will be presenting “10 Channel, 100Gbit/s per Channel, Dual Polarization, Coherent QPSK, Monolithic InP Receiver Photonic Integrated Circuit” on Monday, March 7th at 3:15 pm.
