Design of Porous Core Fiber for Terahertz Regime using Zeonex

Abstract

In this research work, we have designed a Zeonex based single-mode microstructured fiber consisting of a suspended slotted core for THz wave guidance. Full-vector finite element method with perfectly matched layer boundary conditions will be used to investigate the wave guiding property including single-mode operation, dispersion, effective material loss, birefringence, confinement loss, core power fraction, the modal effective area of the fibers. We have selected a most recent cyclo-olefin polymer (COP) based material, trade name Zeonex, as the background material for its unique advantages over other materials. Moreover, it has lower particular gravity, chemical resistance at lifted temperature, higher straightforwardness, lower melt flow index, etc. Furthermore, the physical properties of Zeonex are also suitable for high-quality fiber drawing. This proposed fiber can effortlessly be manufactured using extrusion technology and be used for polarization maintaining applications in THz band.
