Abstract
A novel porous core photonic crystal fiber (PC-PCF) is proposed in this article for efficient transmission of terahertz (THz) wave. The propagation characteristics of the proposed design are investigated by finite element method based COMSOL v 4.2 software. The proposed PC-PCF offers ultrahigh birefringence of order of 10â2 and low effective material loss (EML) of 0.07 cmâ1 at an operating frequency of 1 THz. Moreover, the proposed structure exhibits very low and nearly zero flattened dispersion of 1.1 ± 0.02 ps/THz/cm in the frequency ranging between 0.8 and 1.2 THz. In addition, very low bending loss of 5.45 Ã 10â9 dB/m is observed when bending radius is 1 cm. Other important guiding characteristics such as confinement loss, effective area etc. of the proposed fiber is discussed rigorously. This structure can be a promising candidate for different applications in THz regime.
