Abstract

In this paper, the authors have designed two structures of Photonic crystal fiber. These structures consist of 4 rings of Hexagonal and octagonal air holes. PML and Scattering Boundary condition is applied on these photonic crystal fiber structures. The Finite Element Method of COMSOL Multi Physics is used to design these proposed structures and MATLAB is used to plot the effective refractive index and confinement loss in various cases. It has been observed that the effective refractive index and confinement loss not only varies by change in wavelength, but also by changing the structural parameters of air holes, such as diameter (d) of air holes and pitch (Λ) at 1.55 μm wavelength. The effective area of Hexagonal and Octagonal PCF at 1.55 μm wavelength are 163.45 μm2 and 217.425 μm2 , respectively.
