2012年12月15日至24日间，美国堪萨斯大学（University of Kansas） 电气工程与计算机科学学院教授，本校客座教授惠荣庆博士应邀访问我校。12月20日上午，惠博士在西区电三楼314会议室做了一场题为“From Nonlinear Fiber-optics to Nonlinear Spectroscopy”的学术报告。该报告会是研究生教育创新研究计划之高水平前沿系列讲座之一，由电子工程与信息科学系光波实验室朱冰教授主持。来自电子工程与信息科学系和光学工程系的数十位老师和研究生参加了报告会。

　　惠博士以自己多年来在非线性光纤及其光通信应用方面的相关工作为切入点，深入浅出地介绍了半导体激光器和放大器以及光纤中存在的四波混频现象、WDM光纤通信系统中的交叉相位调制、拉曼串扰及其对光纤通信系统的影响，非线性光纤中的孤子自频移等相关基础知识。在此基础上着重介绍了他目前与化学系跨学科合作开展非线性光谱学方面的最新研究工作。讲解了通过在CARS光谱中引入啁啾脉冲信号提高频谱的分辨率，以及SRS光谱和CARS光谱在细胞显微成像中的应用方面的研究成果；并对这些研究成果之间的内在联系进行了深入的分析讨论。通过这一系列工作惠博士向大家展示了学科交叉与学术沟通对科研工作的重要启发作用，引起了与会同学和老师的强烈反响。报告结束后，他和参会的老师同学们就讲座的相关内容进行了热烈的讨论。

　　惠荣庆教授简介

　　Dr. Rongqing Hui received the B. S. and M.S. Degrees from Beijing University of Posts and Telecommunications, China in 1982 and 1988, respectively, and the PhD Degree from Polytechnic University of Torino, Italy in 1993, all in Electrical Engineering.

　　Dr. Hui is a professor of Electrical Engineering and Computer Science, the University of Kansas in Lawrence KS. 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, Dr. Hui was a member of scientific staff at Bell-Northern Research and then Nortel-networks in Ottawa, Canada, where he was involved in the research and development of high-speed optical fiber communication systems. From April 2006 to December 2007, Dr. Hui was Program Director of the Electronics, Photonics and device Technologies (EPDT) program within the ECS division in National Science Foundation with core responsibility for proposals in the areas of Photonics, optoelectronics and optical device technologies. From May 2001 to July 2007, Dr. Hui was Associate Editor of IEEE Transactions on Communications. From July 2006, he is Associate Editor of IEEE Journal of Quantum Electronics.
