摘要
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.
