Terahertz pulse propagation in a plastic photonic crystal fiber

Guided-wave single-mode propagation of subpicosecond terahertz (THz) pulses in a plastic photonic crystal fiber has been experimentally demonstrated. The plastic photonic crystal fiber is fabricated from high-density polyethylene tubes and filaments. The fabricated fiber exhibits the low loss and relatively low dispersive propagation of THz pulses within the experimental bandwidth of 0.1-3 THz.
