Innovations in Terahertz Interconnects: High-Speed Data Transport Over Fully Electrical Terahertz Waveguide Links

The continued increase in computing capability that has occurred through the technology scaling foretold by Moore [1] and Dennard et al. [2] has led to a commensurate increase in the input-output requirements of computing systems. This phenomenon has been most significantly experienced in terms of the interconnect technologies in large data centers (DCs) and high-performance computing (HPC) applications. Historical data have shown a two to three times increase in aggregate data rates every two years [3]. This space covers a variety of different interconnect length scales. In a comprehensive survey by Thraskias et al. [4], high-speed interconnects are grouped according to the following taxonomy.
