Terahertz Dielectric Waveguide based on Silicon-on-Insulator Technology

In this paper, a low-loss dielectric waveguide is implemented in silicon-on-insulator (SOI) technology working at the terahertz range of frequencies. The waveguide characteristics are investigated to support fundamental mode using full-wave simulations. A properly designed rectangular grid is utilized to handle the waveguide with minimized effect on the insertion loss of guiding channel.
