Abstract

We propose a new structure of broadband nearly-zero flattened dispersion highly nonlinear photonic crystal fiber (PCF). Through optimizing the diameters of the first two inner rings of air-holes and the GeO2 doping concentration of the core, the nonlinear coefficient is up to 47 W-1 km-1 at the wavelength of 1.55 \mum and nearly-zero flattened dispersion of \pm 0.5 ps/(nm km) is achieved in the telecommunication window (1460-1625 nm). Due to the use of GeO2-doped core, this innovative structure can offer not only a large nonlinear coefficient and broadband nearly-zero flattened dispersion but also low leakage losses.
