摘要
A 2-D photonic crystal waveguide with strong pass-bands in the THz frequency range is demonstrated. The 2-D metallic photonic crystal waveguide structure is bounded by parallel metal plates in the vertical direction and by a square lattice of metallized cylinders on the horizontal axis. The attenuation of the photonic crystal waveguide is experimentally determined and compared to the fundamental mode of a comparably sized rectangular waveguide. The measured dispersion characteristics of the waveguide are discussed, and the output is compared to a finite-difference time-domain simulation.
