Shlomi Arnon Ben-Gurion University of the Negev Electrical and Computer Engineering Department Optical Wireless Communications For Next-Generation Data Centers Abstract Data centers collect and process information with a capacity that has been increasing from year to year at an almost exponential pace. Traditional fiber/cable data center network interconnections suffer from bandwidth overload, as well as flexibility and scalability issues. Therefore, a technology-shift from the fiber and cable to wireless has already been initiated in order to meet the required data-rate, flexibility and scalability demands for next-generation data center network interconnects. In addition, the shift to wireless reduces the volume allocated to the cabling/fiber and increases the cooling efficiency. Optical wireless communication (OWC), or free space optics (FSO), is one of the most effective wireless technologies that could be used in future data centers and could provide ultra-high capacity, very high cyber security and minimum latency, due to the low index of refraction of air in comparison to fiber technologies. In this talk we review the main concepts and configurations for next generation OWC for data centers. Two families of technologies are reviewed: the first technology regards interconnects between rack units in the same rack and the second technology regards the data center network that connects the server top of rack (TOR) to the switch. Measurement results in operational data center are presented. Speaker Bio Shlomi Arnon is a Professor at the Department of Electrical and Computer Engineering at Ben-Gurion University (BGU), Israel. Professor Arnon's honors and awards include SPIE Fellow and Fulbright Fellow. During 1998-1999 Professor Arnon was a Postdoctoral Associate (Fulbright Fellow) at LIDS, Massachusetts Institute of Technology (MIT), Cambridge, USA. His research has produced more than eighty journal papers in the area of optical, satellite and wireless communication. During part of the summer of 2007, he worked at TU/e and PHILIPS LAB, Eindhoven, Nederland on a novel concept of a dual communication and illumination system. He was visiting professor during the summer of 2008 at TU Delft, Nederland. During the year 2011-2012 he took sabbatical leave at the Silicon nano photonic Lab, Cornell University, USA. He is/was an associate editor for the Optical Society of America - Journal of Optical Networks in 2006, and the IEEE Journal on Selected Areas in Communications for a special issue on optical wireless communication in 2009 and 2015. He is co-author of the book Applied Aspects of Optical Communication and LIDAR, Taylor & Francis/ CRC, 2010 a co-editor of the book Advanced Optical Wireless Communication Systems, Cambridge University Press, 2012 and editor of the book Visible Light Communication Cambridge University Press, 2015. In addition to research, Prof Arnon and his students work on many challenging engineering projects with especial emphasis on the humanitarian dimension. For instance, a long-standing project has dealt with developing a system to detect human survival after earthquakes, or Infant respiration monitoring system to prevent cardiac arrest and Apnea. Faculty Host: Professor Little Refreshments will be served outside of PHO 339 at 10:45.
