This article presents an excellent design of a quasi-shape of cladding with elliptical shape based rotated-hexa core in photonic crystal fiber for terahertz applications. The designed Q-PCF fiber achieves ultra-low effective material loss in the terahertz regime and shows single mode propagation over a wide frequency range. This Q-PCF fiber is expected to be suitable for efficient transmission in terahertz communication networks.
In this article, an excellent design of a quasi-shape of cladding with elliptical shape based rotated-hexa core in photonic crystal fiber (Q-PCF) has been presented for terahertz (THz) area. For wide area based communication networks, our suggested PCF fiber (Q-PCF) is strongly useful because of achieving by ultra-low effective material loss (EML) in the terahertz regime. Finite element method (FEM) and perfectly matched layers based on COMSOL software tool is used to design this Q-PCF fiber. After simulation procedure, our PCF discloses an ultra-low effective material loss (EML) of 0.0162 cm(-1), power fraction in the core area and large effective area of 73%, and 5.45 x 10(-8) mu m(2) respectively, at 1 terahertz (THz) frequency range. In addition, other optical fiber properties such as confinement loss, scattering loss, and V-parameter have also been explained with a suitable graphical process here. Moreover, our reported quasi-photonic crystal fiber (Q-PCF) shows single mode propagation by V-parameter indicator over 0.80 to 3 THz frequency regions. So, we hope that our designed Q-PCF fiber will be suitable for efficient transmission and many communication networks of terahertz (THz) signal of system.
