Abstract

A novel Nearly Zero Dispersion Fiber (NZDF) at operating wavelength is designed having GeO₂ doped SiO₂ square defected core and investigated with Finite Element Method (FEM) using COMSOL. The proposed PCF shows promising dispersion characteristics (0.0001787ps/km-nm) with very low effective area (3.03μm²) and high non-linear parameter (67.23 W^-1 km^-1) at 1.55μm, making it suitable candidate for chromatic dispersion controller and nonlinear optical application.
