Propagation of Terahertz Pulses in Photonic Crystal-Based Rib Silicon Waveguides

Terahertz link with orthogonal polarization over silicon dielectric waveguide

“…This phenomenon is in contrast with metallic waveguides, which tend to experience more loss at higher frequencies because of the skin effect of metal [14]. Si waveguides have also enabled fundamental applications for the generation of THz waves through wavelength conversion [15,16]. However, the limitations of state-of-the-art equipment limit the highest achievable transmission data rates in the THz region.…”
