Abstract

Silicon-based Terahertz systems is a field that is only about a decade old. During this time, we have seen a phenomenal growth of silicon systems operating at THz frequencies for a wide range of applications in sensing, imaging and communication. It can be argued that both the ‘THz gap’ and the ‘technology and applications gap’ are closing in meaningful ways in the THz range. Technologies beyond 100 GHz focusing on sensing, imaging and wireless back-haul links are getting attractive as we enter into a new area of highly dense network of autonomous systems requiring ultra-high speed and reliable links. In this talk, I will highlight approaches that cut across electromagnetics, circuits, systems and signal processing to enable THz beamforming arrays, programmable THz metasurfaces with CMOS tiling and physically secure sub-THz links (Nature Elec’21, Nat Elec’20, Nat Comm’19, Nat Elec’18). In the end, I will comment on whether AI can help in the synthesis of these complex ICs.
