摘要：

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 1.8×10-15dB/cm at the same operating frequency. It promises the aforementioned advantages for efficient THz wave propagation. © 2020 Walter de Gruyter GmbH, Berlin/Boston 2020.
