The proliferation of high-speed consumer connections due to newer services such as high-definition TV and the increase in personalized data content has led to significant connectivity bottlenecks in data centers, campus networks, high-performance computing clusters and storage area networks. Internet exchanges and network centers have expanded to as many as 100,000 optical fibers routing traffic at speeds of 10 gigabits per second (Gbps). The availability of cost-effective interfaces operating at data rates of 100 Gbps now, and terabits per second Tbps (1,000 Gbps) in the not-so-distant future will reduce the numbers of fibers and transceivers by a factor of 100, greatly reducing wiring complexity and equipment and operating costs in high-capacity fiber-optic networks. CyOptics and joint-venture partner Kotura, Inc. (Monterey Park, Calif.) have proposed developing new optical components and processes to make Terabit Photonic Integrated Circuits (TERAPICS) that can transmit and receive up to one Tbps of data over one single-mode fiber across transmission distances of up to two kilometers. The project will reduce hundreds of individual components to fewer than 10. Instead of overseas hand assembly, TERAPICS will be assembled mainly on Cy0ptics' U.S.-based highly automated assembly platform. CyOptics will develop monolithic arrays of high-speed CWDM (coarse wavelength division multiplexing) lasers, detectors and new automated assembly processes. Kotura will develop two highly integrated silicon photonics chips, one for data multiplexing/transmission and one for data demultiplexing/detection. A major technical challenge is assuring an adequate amount and quality of light reaching the detector for each wavelength channel. If successful, the new technology could reduce costs and complexity across the entire telecommunications sector, including component and module manufacturers, system integrators, service providers and end users.
