UANews: “Researchers from the University of Arizona, the University of Southern California and seven other institutions are attempting to save the Internet by making it cheaper, faster and better. With the rising demand for Internet access outstripping the existing Internet capacity, scientists are turning to optoelectronic technology – transmitting data using light. The technology is well-established but is still being developed in order to handle the increasing data loads that users require.

UANewsIn 2008, the National Science Foundation gave a five-year, $18.5 million grant to establish an engineering research center that is based at the UA and unites it with USC and the other universities in a collaboration known as the Center for Integrated Access Networks, or CIAN. CIAN’s goal is to solve the data crisis by bringing optoelectronic technology to its full potential.

“CIAN is aimed at transforming the Internet to a high-speed network that uses less energy, is more reliable so that it reconfigures itself around network impairments, is scalable to make it suitable for a growing number of end users, and is not too costly,” said Nasser Peyghambarian, chair of photonics and aasers in the College of Optical Sciences at the UA.

“The UA and USC and seven other university partners are working together on improving the reliability of the network as well as the network speed and cost,” he said.

Other partner institutions in the CIAN are the University of California, San Diego; the California Institute of Technology; University of California, Los Angeles; University of California, Berkeley; Columbia University; Norfolk State University and Tuskegee University.

“We’re using optics to enable higher capacity communications,” said Alan Willner, Steven and Kathryn Sample Chair in Engineering of the USC Dornsife College. Willner and Columbia professor Keren Bergman are leading the system and networking research for the group. “I can send 10 gigabits per second across the backbone of the national network,” Willner said. “The problem is, how do you get 10 gigabits to every home, every access point?”.

“Todays indispensible Internet was achieved through advances in optical communication technology, which dramatically reduce communication cost per unit information volume and transmission distance. The next-generation Internet, as infrastructure to support a future ubiquitous environment, will require even more advances in optical communication technology. Accordingly, the Tsuda Laboratorys research theme is making communications optical. The Lab aims to enable further progress in network infrastructure by researching optical circuits, photonic networks, and ultrafast optical signal processing.”
