香港中文大学光子学研究进展及 图像处理技术在光OFDM信号监测中的应用 Introduction to Photonics Research at The Chinese University of Hong Kong, and Use of Image Processing Techniques for Optical Signal Monitoring in Optical OFDM Systems

报告摘要：

报告主要包括两部分内容：首先，简单介绍香港中文大学信息工程系光子学研究组的情况，此部分将重点介绍最近在研的主要科研项目。然后，详细讨论我们最近提出的图像处理技术在OFDM光信号性能监测中的应用，主要包括公共相位误差估计和调制格式识别两大内容。这将为实现基于数字信号处理（DSP)算法的高效光信号性能监测开辟全新的途径。

In this talk, I will first briefly introduce the Photonics Research Group at the Department of Information Engineering, The Chinese University of Hong Kong. Several on-going research projects will be highlighted. Then, I will present our recent projects on the use of image processing techniques to perform optical signal monitoring in optical OFDM systems, which include common phase error estimation and modulation format recognition. These offer another efficient and effective option to support digital signal processing for optical performance monitoring.

报告人介绍：

Calvin Chan教授在香港中文大学获得博士学位后，于1999年加入美国朗讯科技公司Bell实验室，主要从事于宽带可调谐半导体激光器和Tb/s大容量光分组交换方面的研究。2001年加入美国Jedai Broadband Network 公司担任高级光学系统工程师，从事光接入网和光无线网络设计工作。同年8月，回到母校香港中文大学信息工程系工作，于2011年晋升为教授。Calvin Chan教授已经发表了250多篇期刊和会议论文，曾在2005-2007年和2011-2013年担任光通信旗舰会议OFC的技术程序委员会成员，同时还多次担任其它国际光通信会议的共同主席或组委会成员。Calvin Chan教授目前的研究兴趣包括光传输技术、光城域/接入网络、光信号处理和光性能监测技术。

Prof. Chan received his Ph.D. degree from the Chinese University of Hong Kong. In 1999, he joined Bell Laboratories, Lucent Technologies in Holmdel, NJ, as a Member of Technical Staff, where he worked on control of widely-tunable semiconductor lasers and realization of an optical packet switch fabric with terabit-per-second capacity. In 2001, he served as Senior Optical System Engineer at Jedai Broadband Networks, Inc. in NJ, USA where he worked on the design of optical access networks and optical-wireless systems. In August 2001, he moved back to Hong Kong and joined Department of Information Engineering at the Chinese University of Hong Kong, and now serves as Professor. He has published more than 250 technical papers in refereed international journals and conferences. He served as a technical program committee member for the flagship conference OFC for 6 years, and also served as co-chairs or program committee members in many international conferences in optical communications. His research interests include optical transmission, optical metro/access networks, optical signal processing and optical performance monitoring.
