- Abstract
A near zero dispersion flattened porous core photonic crystal fibre having ultra-flat low material loss suitable for terahertz (THz) transmission is represented. A novel type of geometrical structure of air hole position has been proposed in this design. Numerical analysis exhibits effective material loss (EML) of 0.03746 cm-1 at 1.0 THz operating frequency and a flat EML of 0.0398 cm-1 from 1.5 to 5.0 THz with absolute EML coefficient of ±0.000416 cm-1. The proposed waveguide shows near zero flat dispersion of 0.4 ± 0.042 ps/THz/cm in the frequency range from 1.25 to 5.0 THz.
