Abstract:

Chromatic dispersion (CD), polarization mode dispersion (PMD), nonlinear effects, and loss are important issues on the physical layer of fiber optical communication and sensor systems. It is essential that these degrading physical effects be well managed in the optical fiber systems. One the other hand, they can also be beneficial and have applications on optical signal processing and sensing.  This presentation gives a brief review of the recent research of my group in this area, including: digital carrier recovery in coherent optical communication system based on decision-aided maximum likelihood (DA ML) algorithm; optical performance monitoring; and non-invasive smart health monitoring system based on optical fiber sensor.

Biography:

Dr. Changyuan YU received his B.S. in Applied Physics and B. Economics in Management from Tsinghua University, China in 1997, M.S. in Electrical and Computer Engineering from University of Miami, USA in 1999, and Ph.D. in Electrical Engineering from University of Southern California, USA in 2005.  He joined Department of Electrical and Computer Engineering, National University of Singapore (NUS) in 12/2005 and served as the founding leader of Photonic System Research Group in NUS. He was also a joint senior scientist with A*STAR Institute for Infocomm Research (I2R).  In 12/2015, he joined Department of Electronic and Information Engineering, The Hong Kong Polytechnic University as an associate professor. 

His research focuses on photonic devices, subsystems, optical fiber communication and sensor systems, and biomedical instruments.  As the PI/co-PI, he secured over 4 million US dollars grants, and supervised 8 postdocs and 20 PhD students.  He has authored/co-authored 1 US patent, 6 book chapters and over 360 journal and conference papers (66 invited, including OFC2012 in USA).  He has served in technical program committee (TPC) or organizing committee for 80+ international conferences (including TPC member of OFC2014-2016, general chair of SPPCom2015, and TPC chair of SPPCom2014 in USA).  His group won 6 best paper awards in conferences and also the championship in biomedical area in the 3rd China Innovation and Entrepreneurship Competition (out of 10,000+ competitors) in 2014.
