Low Loss Topas Based Single Mode Photonic Crystal Fiber for THz Wave Propagation
Abstract
A suspended topas based porous-core fiber with square lattice-shaped core is proposed in this design. To obtain low loss waveguide in THz it is now a challenge cause most of the materials are highly absorbent to THz waves. We propose a design that shows an extremely low effective material loss (EML) of only 0.017 cm−1 for 330µm core length at 1.0 THz operating frequency. The proposed design exhibits a negligible confinement loss of only 4.011 ×10−05 cm−1 and low dispersion at the optimal design parameters. We also have discussed single-modeness and the power fraction and thoroughly.
