Tutorial - We.D.1.T Recent Advances and Future Perspectives in OWC, FSO Communication and Sensing

Chi-Wai Chow National Yang Ming Chiao Tung University

Optical wireless communication (OWC) is an emerging area where research and development are growing worldwide. This is due to the tremendous demands for high-bandwidth communications. The radio-frequency (RF) spectral resource in traditional communication band has be exhausted, and frequency allocation will be a big issue, particularly for the future 6G networks. The non-terrestrial-networks (NTN) in 6G introduce new applications, such as automatic logistics with drones, satellite communication, underwater communication, etc, making OWC inevitable for such ultra-broadband and secure wireless transmissions. This tutorial covers the recent advances and future perspectives in OWC, free-space-optical (FSO) communication and sensing, from devices to applications.

Speaker Biography Chi-Wai Chow received the B.Eng. (1st Class Hons.) and Ph.D. degrees from the Department of Electronic Engineering, the Chinese University of Hong Kong (CUHK), in 2001 and 2004, respectively. From 2005 to 2007, he was a postdoctoral research scientist involved mainly in two European Union Projects: photonic integrated extended metro and access network (PIEMAN) and transparent ring interconnection using multi-wavelength photonic switches (TRIUMPH) with the Department of Physics, Tyndall National Institute, University College Cork, Ireland. In 2007, he joined the Department of Photonics, National Yang Ming Chiao Tung University, Taiwan, where he is currently a full Professor. He currently serves as associate editors of the IEEE/OPTICA Journal of Lightwave Technology and the IEEE Photonics Journal, and technical program committee members of conferences, such as OFC, ECOC, etc. He has authored or co-authored more than 600 papers in journals and conferences. He is an OPTICA (formerly OSA) Fellow.
