2017年3月3日，英国牛津大学Dominic O’Brien教授应徐正元教授邀请做了一场题为“Wireless communications using light: current status and future prospects ”的学术报告。报告会由龚晨教授主持，共50余名师生参加。此次报告会得到了“中科院无线光电通信重点实验室系列讲座”的支持，由中科大信息科学技术学院、中科院无线光电通信重点实验室承办。

在报告中，Dominic O’Brien教授首先指出目前无线通信应用需求日益增长，无线系统需要新的频谱资源和更高的载波频段。无线光通信具有超大容量，频谱资源不受限等优势，是极具应用前景的研究技术。随后，Dominic O’Brien教授分别从红外和可见光两方面介绍了无线光通信的研究现状及目前遇到的问题和挑战。最后，Dominic O’Brien教授展示了多个前沿光通信系统，并对未来无线光通信研究进行了展望。报告结束后，Dominic O’Brien教授与在座的老师和同学们进行了深入的交流，达到了学术交流迸发思想的目的。

报告人介绍：

Dominic O’Brien is a Professor of Engineering Science at Oxford and leads the optical communications group. He is also co-director for systems engineering for the Oxford Led Networked Quantum Information Technologies (NQIT) hub. He gained MA(1991) and PhD (1993) Degrees from the Department of Engineering at the University of Cambridge. From 1993-1995 he was a NATO fellow at the Optoelectronic Computing Systems Center at the University of Colorado.

He has a range of experience in optoelectronics research in industry (BT labs) and academia, and has authored or co-authored more than 200 publications in this area. The group has a wide range of experience in free space optical communications and optical wireless, demonstrating integrated optical wireless transceivers, a full room-scale system at 300Mbit/s, integrated visible light communications systems, and free-space communications systems with unmanned aerial vehicles.
