Abstract :
We theoretically and experimentally investigated the fabrication conditions for THz photonic crystals. A THz photonic crystal with complete band gap from 0.33 THz to 0.36 THz has been designed. The substrate is polytetrafluorethylene (PTFE) which is transparent in THz range. The lattice constant is 320 ¿m, the hole radius is 85¿m. An excimer laser with wavelength 248nm is used to realize the structure. According to a series of testing results, the optimized conditions for this THz photonic crystal fabrication have been confirmed. The excimer laser energy is 13 mJ and the pulses number per burst is 120.
