biostudies-literatureUnknown16(1)Blatter TA promising approach to increase wireless capacity is the transition to sub-Terahertz carrier frequencies (0.1-0.3 THz). While traditional high-frequency approaches employ III-V semiconductor technologies, plasmonics is emerging as a potential solution for highest-speed components. In this paper, we introduce an all-plasmonic sub-THz wireless link, utilizing compact (<50 µm²) plasmonic components that exhibit a flat frequency response up to 300 GHz while providing full flexibility in carrier frequency selection. The plasmonic approach offers unprecedented integration potential, compatibility with diverse platforms, and scalable, cost-effective fabrication. To demonstrate its capabilities, we conduct a lab experiment transmitting 120 Gbit/s on a 285 GHz carrier across a 5 m free-space link,Nature communications9988https://www.ebi.ac.uk/biostudies/studies/S-EPMC12615664biostudies-literatureAll-plasmonic sub-terahertz wireless communication link.PMC12615664Destraz MLeuthold JHess SHorst YSmajic JZuerrer AFedoryshyn YKoepfli SMKulmer LBlatter TRieben DBaumann MfalseAll-plasmonic sub-terahertz wireless communication link.A promising approach to increase wireless capacity is the transition to sub-Terahertz carrier frequencies (0.1-0.3 THz).
