Abstract
A terahertz waveguide includes an input segment, a transmission segment and an output segment. The input segment includes an input waveguide and an input microstructured waveguide. One end of the input waveguide is connected with one end of the core of the input microstructured waveguide. The transmission segment includes at least a sub-wavelength waveguide, an air cladding surrounding the sub-wavelength waveguide and a solid outer cladding surrounding the air cladding. The other end of the core of the input microstructured waveguide is connected with one end of the sub-wavelength waveguide. The other end of the sub-wavelength waveguide is connected with the core of the output microstructured waveguide. One end of the solid outer cladding is connected with the cladding of the input microstructured waveguide, and an output segment. The output segment includes an output microstructured waveguide and an output waveguide.
