摘要：

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 GeO;doping concentration of the core,the nonlinear coefficient is up to 47 W;.km;at the wavelength of 1.55μm and nearly-zero flattened dispersion of±0.5 ps/（nm·km） is achieved in the telecommunication window （1460-1625 nm）.Due to the use of GeO;-doped core,this innovative structure can offer not only a large nonlinear coefficient and broadband nearly-zero flattened dispersion but also low leakage losses.
