Abstract
We propose a dispersion flattened and high birefringence terahertz photonic crystal fiber using roll up method with PTFE. The PCF made of this method shows dispersion flatness by the air region between PTFE tubes around core and high birefringence by asymmetric mode distributions. When using rod with Dout = 1mm, dispersion of the proposed THz PCF has a slope of 0.4ⅹ10-2 near 0.848 THz and the value of the then is about 0.21 ps/THz.cm. In this structure, the order of birefringence is 10-3 and the order of confinement loss is about 10-11 dB/m.
