Design and Comparison of SF57 Over SiO2 on Same Structured PCF for Residual Dispersion Compensation

Two square photonic crystal fibers (SPCFs), one made of silica (SiO 2 ) and the other made of high index lead silicate soft glass (SF57), are numerically analyzed, compared, and proposed in this paper.

Summary:Two square photonic crystal fibers (SPCFs), one made of silica (SiO 2 ) and the other made of high index lead silicate soft glass (SF57), are numerically analyzed, compared, and proposed in this paper. Both designs of SPCFs show very high negative and ultraflattened chromatic dispersion with very low variation of dispersion (ΔD). P-1 offers -650(+6) ps/(nm.km) for the wavelength range of 1.46 → 1.63 μm and bandwidth (BW) = 170 nm and P-2 offers -693(+4) ps/(nm.km) for the wavelength range of 1.45 → 1.68 μm (BW = 230 nm) with average high birefringence of the order of 10 -2 . The proposed designs can be suitable for residual dispersion compensation while maintaining polarization due to having the properties of high negative flattened chromatic dispersion with high birefringence. The influence of changing the structural parameters up to +0.02μm are also examined for ensuring the flatness of the property of chromatic dispersion within the acceptable level.
