摘要：
A kind of lead silicate photonic crystal fiber (PCF) is proposed in this paper. The dispersion characteristics of this SF57 PCF are studied by the finite element method. The reasults demonstrate that the PCF presents all-normal dispersion profiles in the visible and infrared spectral regions. We use an adaptive split-step Fourier method to study the propagations of the 1550 nm and 150 fs laser pulse in the PCF. The resulting spectral profiles are extremely flat from 1300 nm to 1900 nm and have excellent stabibities and coherence properties.
