Abstract

A THz hollow-core Bragg waveguide constructed by cascading waveguide units with supporting bridges on different air rings is proposed. The influence of the supporting bridges on the transmission loss of the waveguide is demonstrated numerically. Results show that the supporting bridges in the first air ring play the most important role on the transmission loss. By reasonably selecting the length ratio of the waveguide units, the waveguide transmission loss can be reduced to less than 0.5 dB/m in range from 0.572 to 0.62THz, and the loss of the proposed Bragg waveguide are close to those of the IHC Bragg waveguide.
