Title
Extremely Low Loss of Photonic Crystal Fiber for Terahertz Wave Propagation in Optical Communication Applications
Abstract
An enormously low loss symmetrical hybrid decagonal porous core spiral photonic crystal fiber (SH-PCF) has been proposed for terahertz (THz) wave guiding. The modal characteristics of the fiber and its mathematical analysis have been numerically completed using a full-vector finite element method (FEM). Simulation results show an ultra-low material loss of 0.0167 cm−1 and large effective area 1.95×106 µm2 which is 91.6 % of bulk absorption material loss at controlling frequency f=1.0 THz with a core porosity 42 %. Additionally, proposed structure establishes the comparatively higher core power fraction maintaining lower scattering loss about 1.8×10−15 dB/cm at the same operating frequency. It promises the aforementioned advantages for efficient THz wave propagation.
