Multifunctional Photonic Crystal Fiber Based on 1x4 Powerful Splitters

Abstract

Optical fiber is the preferred medium for transmitting information in modern times. However, to keep up with the growing demands spurred by the internet's expansion, continuous enhancement of fiber propagation properties is imperative. A new generation of fibers aims at reducing losses and enhancing overall performance compared to traditional counterparts. This study introduces a hexagonal photonic crystal fiber (PCF) design for analyzing various optical properties across different wavelengths. The geometry is utilized to examine parameters such as effective refractive index, dispersion, effective mode area, nonlinearity coefficient, and birefringence. Silica glass is selected as the base material, with the cladding area composed of layers of air holes. The research focuses on modeling and analyzing wave propagation characteristics in optical crystal fibers. Keywords: finite-element methods (FEMs), microstructured fibers, optical fiber devices, photonic crystal fiber, power splitter
