This talk will review prospects for the Future Internet enabled by integrated photonic system technologies. The talk will be in three parts. We will first discuss the role of optics in the Internet architecture. The new BGP with crosslayer monitoring and management based on parallel optical wavelengths enables a new Internet architecture that supports higher throughput and improved stability. In the second part of the talk, we will introduce networking and computing systems with new photonic technologies. We will discuss high-throughput and low-latency optical-label switching routers at the core, optical-CDMA at the edge, interfacing with wireless/wireline legacy networks. We will also introduce future computing systems with nanophotonic interconnects to support ‘balanced computing’ emphasized by Amdahl’s Law which predicts optimum system performance when processing, memory, and communication are balanced. During the final part of the talk, we will discuss the details of nanophotonic and nanoelectronic technologies that enable the future computing and networking systems. CMOS-compatible silicon photonics offer a practical platform for routing and transporting multi-wavelength optical signals interconnecting electronic processors and memories. Potentially, such a system can grow to a ~1000 core system optically interconnected by 100~1000 wavelengths where a flat-hierarchy computing architecture becomes possible. We will give a number of device and system examples, and conclude by projecting the future cyberinfrastructure filled with integrated chip-scale photonic networking and computing systems.
S. J. Ben Yoo serves as Director of UC Davis CITRIS (Center for Information Technology Research in the Interest of Society) and Professor of Electrical Engineering at University of California at Davis (UC Davis). His research at UC Davis includes future Internet architectures, high-performance optical switching systems, nano photonic-electronic systems integration for next generation networking and computing systems. His recent demonstrations included optical label switching routers with 1000 times improvement in performance/power efficiency over conventional electronic routers. Prior to joining UC Davis in 1999, he was a Senior Research Scientist at Bellcore, leading technical efforts in optical networking research and systems integration for DARPA sponsored MONET and NGI projects. He also participated in the advanced technology demonstration network/multiwavelength optical networking (ATD/MONET) systems integration, and a number of standardization activities. Prior to joining Bellcore in 1991, he conducted research on nonlinear optical processes in quantum wells, a four-wave-mixing study of relaxation mechanisms in dye molecules, and ultrafast diffusion-driven photodetectors at Stanford University (BS’84, MS’86, PhD’91, Stanford University). Prof. Yoo serves as an Associate Editor for IEEE Photonic Technology Letters, and Guest Editor for IEEE/OSA Journal of Lightwave Technology, IEEE Journal of Special Topics in Quantum Electronics, and OSA Journal of Optical Networks. Prof. Yoo is a Fellow of IEEE, a Fellow of OSA, and a recipient of the DARPA Award for Sustained Excellence in 1997, the Bellcore CEO Award in 1998, and the Mid-Career Research Faculty Award (UC Davis) in 2004.** Prof. Yoo will be available for meeting with students.
