Design of Octagonal and Decagonal Lattice Photonic Crystal Fiber for Achieving Ultra Low Flattened Dispersion
This paper presents some key concepts of design and optimization of solid core photonic crystal fiber (PCF) based on different geometries for broadband applications. The three different geometrical structures, hexagonal, octagonal, and decagonal of photonic crystal fiber, are designed for different air filling fractions at pitch length 2 μm. The parameters affecting the light propagation through PCF structure such as effective refractive index, chromatic dispersion, mode effective area, nonlinear coefficient, and V parameter are numerically analyzed and compared using finite element method (FEM) on COMSOL Multiphysics software.
