Dr. Dan Kilper
CIAN Administrative Director
University of Arizona

Dr. Kilper is a research professor in the College of Optical Sciences at the University of Arizona and is currently serving as the Administrative Director for the Center for Integrated Access Networks (CIAN). He holds and adjunct research appointment in Electrical Engineering at Columbia University and received a PhD in Physics from the University of Michigan in 1996. Within both academia and industry, he has made contributions toward research and development of communication devices and networks primarily spanning three areas: energy efficient communication networks, optical performance monitoring, and dynamic optical networks. He is a senior member of IEEE and is an editor for the Green Communications and Computing Networks Series in IEEE Communications Magazine as well as for the IEEE Journal on Selected Areas in Communications (JSAC) Series on Green Communications and Networking. He is a general chair of IEEE Online Greencomm 2014 & 2015. In addition to his current position with CIAN, he has served in leadership positions in multi-university/industry consortia including the Center for Telecommunications Value Chain Research (CTVR), Center for Energy Efficient Telecommunications (CEET), and the GreenTouch Consortium. His work has been recognized with the Bell Labs President’s Gold Medal Award and he served on the Bell Labs President’s Advisory Council on Research. He holds eight patents and authored four book chapters and more than one hundred peer-reviewed publications


Much attention over the past five years has been focused on the fiber capacity crunch. In this talk we will examine different interpretations of the fiber capacity crunch and its ramifications on optical networks. We draw analogies with other similar capacity or performance ‘crunches’ that have occurred in cellular radio and computer systems in order to look for guidance on where optical systems might be going in the post-crunch years. An analysis of the capacity scaling properties of communication networks from the optical core down to the processor core provides further insights on directions that optical networks may take and in particular trends in data center networks point to the growth of metro networks as an important evolutionary step. The maturation of silicon photonics and other integrated photonic technologies are expected to play a key role.
