Nevertheless, communications in the high-frequency band encounter significant challenges owing to their large free-space and penetration losses. THz signal processing, such as relaying, routing, switching, and frequency converting, is crucial to facilitate the deployment of this technology. However, these functions cannot be realized using electronic technologies. In this regard, photonic technology and convergence with its radio counterpart are promising to realize new communication features and applications. In this tutorial, I will present various photonic technologies for THz signal processing, including signal generation, transmission, reception and down-conversion, transparent relay, routing, switching, multiplexing\/demultiplexing, and applications. As an application example, a seamless fiber-radio network in the high-frequency band using an adaptive tracking and switching system for uninterrupted communication for rapidly moving users on high-speed trains will be introduced.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-3a7dc9378e546d0ed7595d167fbea1df\">Biography:<br>Pham Tien Dat received the B.Eng. degree in electronics and telecommunication engineering from the Posts and Telecommunications Institute of Technology, Hanoi, Vietnam, in 2003, M.Sc. and Ph.D. degrees in science from Waseda University, Tokyo, Japan, in 2008 and 2011, respectively. In 2011, he joined the National Institute of Information and Communications Technology (NICT), Tokyo, Japan, where he is currently a Senior Researcher. His research interests include millimeter-\/terahertz-wave photonics, radio-over-fiber, optical wireless systems, and seamless access networks for 6G and beyond. He served as Guest Editor for the IEEE Journal of Selected Topics in Quantum Electronics (Special Issue on Terahertz Photonics) in 2023. He received the 2023 IEICE Electronics Society Award for pioneering research on radio-over-fiber systems and their applications.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dr. Pham Tien Dat, Senior Researcher, National Institute of Information and Communications Technology (NICT), Tokyo, Japan Photonics-enabled terahertz signal processing and applications in 6G and beyond Abstract: Radio communication in the terahertz (THz) band is promising for ultra-high data-rate and low-latency services in 6G and beyond networks.
