Design and analysis of non-linear properties of photonic crystal fiber with Various Doping Concentration

With exceptional light guiding mechanism and deliver significantly improved performance compared to conventional optical fibers, Photonic Crystal Fibers (PCFs) are a new class of optical waveguide. In this work, a solid core photonic crystal fiber (PCF) is designed using Comsol Multiphysics software based on finite element method. In our analysis the structure introduced is a structure formed by a doped core surrounded by a cladding which is composed by elliptical air holes in silica arranged in a hexagonal array. The important optical properties like effective area and nonlinear coefficient has been studied. Each characteristic has been investigated under different doping concentration within range of wavelength 800-1600 [nm].
