Dr. Hui is a professor of Electrical Engineering and Computer Science at the University of Kansas. His research interests are in lightwave communication systems and subsystems, photonic devices, optical instrumentation and photonic sensors. Prior to joining the faculty of the University of Kansas in 1997 he taught undergraduate and graduate courses in optical communications, microelectronic circuits, and semiconductor materials & devices for more than 15 years. Dr. Hui was a member of the scientific staff at Bell-Northern Research and Nortel in Ottawa, Canada, where he was involved in the research and development of high-speed optical transport networks. He was a NSF Program Director for the photonic devices program from 2006 to 2008. He served as an associate editor for IEEE Transactions on Communications from 2001 to 2007 and an associate editor of IEEE Journal of Quantum Electronics from 2006 to 2013. Maurice O’Sullivan has engineered the physical layer of optical transmission for more than 30 years, at first in the optical cable business, developing factory-tailored metrology for optical fiber, but, mainly, in the optical transmission business developing, modeling and verifying physical layer designs and performance of Nortel's (now Ciena’s) line and highest rate transmission product including the first commercial 10 Gb/s system, several commercial terrestrial line systems, the first commercial DSP assisted electric field modulation transceiver with complete electronic compensation for optical dispersion and the first commercial coherent 40Gb/s and 100Gb/s transceivers. Now with Ciena, Maurice is engaged in the design of successive generations of flexible high capacity multi-rate coherent transceivers including 50G/100G/200G, 100G/…/400G, and 200G/…/800G products. Maurice is a Ciena Fellow with more than 45 patents and holds a Ph.D. in physics (high resolution spectroscopy) from the University of Toronto.
