Jian Zhao

Biography

Jian Zhao received the M.Phil. and Ph.D. degrees from the Chinese University of Hong Kong in 2004 and 2007, respectively. He joined the Photonic Systems Group at the Tyndall National Institute, Ireland in 2007, and is currently a Staff Researcher. Since 2009, he has captured more than €1.1 million funding (direct cost) as a PI from Enterprise Ireland, Science Foundation Ireland, EU FP7, and Irish Research Council. He proposed and experimentally demonstrated the world-first optical fast OFDM at both the 1550-nm and 2000-nm optical wavelengths, and pioneered offset-QAM multicarrier technologies in optical communications. The team he led developed a 10-G real-time electronic-dispersion-compensation integrated receiver prototype supporting >900 km transmission and was the EMEA finalist in Alcatel-Lucent Innovation Competition. He has published 100 papers in peer-reviewed journals and conferences (68 senior-author papers; 16 invited), and 2 book chapters. His current research interests include optical OFDM, advanced modulation and detection schemes, and digital signal processing for optical communications. He is a member of IEEE.
