    Toward Robust Underwater and Water-air Optical Wireless Communication

    Lian-Kuan Chen received a B.S. degree in electrical engineering from National Taiwan University in 1983 and an M.S. and Ph.D. degree in electrical engineering from Columbia University in 1992. He joined the faculty of the Department of Information Engineering at the Chinese University of Hong Kong and established the Lightwave Communications Laboratory in 1992. He was the Department Chairman from 2004 to 2006 and the director of Centre for Advance Research in Photonics from 2010-2014. From 2007 to 2013, he was a member of the engineering panel of the HKSAR research grant council. His research includes underwater optical wireless communications, visible light communication, broadband local access networks, transmission systems, optical performance monitoring, and bio-photonics for medical applications. He has more than 300 research publications and two U.S. patents in the aforementioned areas. He has served as an associate editor of IEEE Photonics Technology Letters (2005-2011) and OSA/IEEE Journal of Optical Communications and Networking (2012-2015). 

    Optical communication has been employed in multitudinous applications, including terrestrial, submarine, inter-satellite, and space communications. It enables optical fiber-based communication networks that vastly reshape modern lives through high-speed worldwide Internet connections. With intensified activities such as undersea resource exploration, ecosystem monitoring, and recreation, underwater is an exciting new arena for optical wireless communication (OWC). The recent progress of underwater and water-air OWC systems and devices will be reviewed. Channel characterization, communication system design, and performance investigations will be given. Critical limitations and effective mitigation methods to realize robust underwater and water-air OWC systems will be discussed. In particular, I will fixate on the recently proposed bubble, wave, and turbulence mitigation methods that leverage spatial diversity, advanced signal processing, and beam control techniques. Capacity enhancement for underwater and water-air OWC systems via wavelength division multiplexing will be presented. Finally, other applications for underwater research will be discussed.
