Abstract
Highly nonlinear fibers with nearly zero flattened dispersion over a wide band range has very wide applications in future high-capacity, all-optical networks. Because of its flexibility of structure design and much larger index contrast between the core and effective cladding than the conventional fibers, photonic crystal fibers (PCFs) are becoming to be an attractive candidate to form this kind of highly nonlinear fibers. Based on quantitative analysis on the effect of the difference of hole-sizes between the first ring and the other's, and the effect of Ge-doped concentration in the core region on the PCF's dispersion curve, a new way to design PCF with high nonlinear coefficient and nearly zero flattened dispersion is proposed. Based on this, a PCF is designed, which has dispersion values between ±0.8ps/nm/km over S+C+L wavelength bands, and the dispersion slope of 0.005ps/nm2/km, nonlinear coefficient of 46.6W-1km-1 at 1.55μm.
