In this paper, we present the design and analysis of a novel hybrid porous core octagonal lattice photonic crystal
fiber for terahertz (THz) wave guidance. The numerical analysis is performed using a full-vector finite element
method (FEM) that shows that 80% of bulk absorption material loss of cyclic olefin copolymer (COC),
commercially known as TOPAS can be reduced at a core diameter of 350 μm. The obtained effective material
loss (EML) is as low as 0.04 cm−1 at an operating frequency of 1 THz with a core porosity of 81%. Moreover, the
proposed photonic crystal fiber also exhibits comparatively higher core power fraction, lower confinement loss,
higher effective mode area, and an ultra-flattened dispersion profile with single mode propagation. This fiber can
be readily fabricated using capillary stacking and sol-gel techniques, and it can be used for broadband terahertz
applications. © 2017 Optical Society of America |
