This letter presents a suspended silicon-on-glass waveguide for broadband single-mode low-loss operation at terahertz frequencies. Measured attenuation constants of the two fabricated waveguides are 0.028 and 0.021 dB/ λ0 (on average) over the operation bandwidths of 420–500 GHz and 500–595 GHz, respectively. The fabrication technique of the waveguide is presented.
