Terahertz Communications Accelerated by Photonic Technologies

May 3, 2023 @ 2:00 pm - 3:00 pm

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.
