Modal analysis of teflon photonic crystal fiber as a terahertz waveguide

We analyze the full vector two-dimensional modal characteristics of teflon photonic crystal fiber (PCF) as a terahertz (THz) waveguide. Finite-difference time domain computational strategy is applied in investigating the THz waveguide characteristics of Teflon PCF. Computational results show interesting single-mode and multi-mode behavior of Teflon PCF in the THz region.
