Abstract

In this paper, a porous-core photonic crystal fiber(PC-PCF)is proposed to minimize the effective material loss for terahertz wave transmission. The full vector finite element method with an ideally matched layer boundary condition is used to characterize the wave guiding properties of the proposed fiber. At an operating frequency of 0.5-1.7THz, simulated results exhibit an extremely low effective material loss of 0.029 cm-1,high core power fraction of 50% and ultra-flattened dispersionof1.03±0.04ps/THz/cmat 90% porosity.Besides, only circular air holes have been used which makes the fiber remarkably simpler. Also, physical insights of the proposed fiber have been discussed. The proposed fiber has thepotential of being a promising candidate for different applications in the THz regime..
