Terahertz Communications Accelerated by Photonic Technologies
Research activities in terahertz (THz) communications have become intensive in response to the rapidly growing data traffic in wireless networks. Within an atmospheric window, a wireless transmission data rate over 100 Gbit/s carried by a single THz band has been achieved. This shows a great potential for terahertz link to serve back-haul connectivity for the future 6G communications, and for intra-/inter-chip communications with large data volume. In this talk, the recent advances in THz communications enabled by photonics will be reported. It will mainly cover THz communications systems adopting the latest transmitter and receiver technologies to achieve high transmission data rate, i.e., Brillouin lasers and Fermi-level managed barrier diodes. Additionally, various high-efficiency and broadband THz components based on all-silicon effective-medium-clad waveguide platform and/ or 3D printing will be introduced including polarization multiplexers, polarization rotators, lens antennas, and circularly polarized antennas. It can be foreseen that all these devices and components can largely benefit future 6G communications.

Biography:
Weijie Gao received Ph.D degree in Electrical Engineering from The University of Adelaide (UoA), Australia in 2022. Since the same year, he has been working as a Postdoctoral Researcher in Nagatsuma’s Laboratory at Osaka University (OU), Japan. From 2016 to 2018, he was a visiting researcher with the Adelaide Applied Electromagnetics Group, UoA. From 2018 to 2021, he was a founding member of Terahertz Engineering Laboratory, UoA.
Dr. Gao was the receipt of the Student Prize in the Asia-Pacific Microwave Conference, 2021 (APMC). His thesis was awarded a Dean’s Commendation for Doctoral Thesis Excellence. In 2022, he was awarded a Doctoral Research Medal and The Gertrude Rohan Memorial Prize from UoA in recognition of his Ph.D. research contributions. In 2022, he was awarded a Young Researcher Award by OU for his contributions in the next-generation communications technologies. He is a member of IEEE MTT-S, APS, and Photonics Society. His current research is mainly focused on THz integrated components (waveguides, antennas, filters, polarization-, frequency-multiplexers, mixers, etc) and communications systems towards 6G communications.
