Design and FEM analysis of Zeonex-Based Porous-Core Holey Fiber over telecom bands

This paper provides a comprehensive analysis of the optical properties of a Zeonex-based porous-core holey fiber (PCHF) operating at 1550 nm. The study looks at critical parameters like dispersion, confinement loss, effective area, nonlinear coefficient, V-number, and bend loss to assess the fiber's performance in optical communication and sensing applications. The aforementioned optical properties are determined using the finite element method, which involves Comsol Multiphysics modeling and simulations. The results indicate that the Zeonex-based PCHF exhibits a significant negative dispersion of -785.7 ps/(nm•km), a confinement loss of 7.098×10^-2 dB/cm, and an effective area of 1.319 µm². The fiber's nonlinear coefficient is measured at 61.46 W^-1 km^-1, with a V-number of 2.21 and a bend loss of 4.939×10^-3 dB/cm. These findings demonstrate the potential of the Zeonex-based PCHF to improve the performance of optical communication systems and sensing technologies. The negative dispersion and low confinement loss indicate that it is suitable for controlling chromatic dispersion and reducing signal attenuation. Furthermore, the effective area and nonlinear coefficient values promote high-power light transmission and efficient nonlinear interactions, whereas the V-number and bend loss parameters demonstrate the fiber's structural robustness and flexibility. Finally, this study emphasizes the promising properties of a Zeonex-based PCHF, arguing for further research and development in advanced photonic applications.
