High Capacity Optical Interconnects
Optical interconnects are being considered for short link data networks as a solution enabling higher aggregate bit rates and lower power consumption. For short link length interconnects, as used in chip to chip interconnects, internal system backplanes and inter-system interconnects such as blade server backplanes, storage area networks and processing clusters, requirements are quite different to those for long distance telecommunications systems. Low power consumption, latency, and size become important criteria in addition to ultra high bandwidth. In order to achieve the projected ultra high capacity and low latency needs, we are considering optical switching fabrics. The optical switch, however, brings significant changes to the interconnect architecture in terms of how routing decisions are made and how contention resolution is managed. I discuss these issues and present our results for a multiwavelength optically switched interconnect.
Madeleine Glick received the PhD degree in physics from Columbia University, for research on optical properties of GaAs based quantum wells. She continued research in this subject as a postdoc at the Physics Dept. EPFL, Switzerland. From 1992-96, she was Research Associate with CERN, on the Lightwave Links Project. She joined GEC Marconi, 1997 to 2001, working on high-speed photodetectors. In 2002, she joined Intel Research. Her current research interests are high capacity, multiwavelength optical interconnects for data networks and digital signal processing to improve performance of these systems. Madeleine is a Fellow of the Institute of Physics and a member of the Optics and Photonics News Editorial Advisory Committee of the Optical Society of America.
