Hexagonal PCF of honeycomb lattice with high birefringence and high nonlinearity

This paper presents an optimum design for highly birefringent micro structured photonic crystal fiber (PCF). This is designed with novel hexagonal PCF of honeycomb lattice cladding with hexagonal shaped air cavities and the kernel of the hive is formed by two oblong air holes. The dispersion characteristics of this novel structure have been analyzed analytically using Finite Element Method (FEM) and reported for dispersion and nonlinear coefficient including other fiber parameter. This structure is optimized with distinctive parameters of fiber geometry like pitch of the core, diameters of elliptical shaped air cavities, cladding region having ample of space assortment of wavelength from 0.1 m to 2.0 m also made of SF57 glass helps in reaching high birefringence and low dispersion through the optimization of the arrangement and diameter of elliptical and hexagonal air holes. The proposed model has been suggested with high nonlinearity for super continuum generation.
