Paper Abstract

A theoretical study of flat supercontinuum (SC) generation in a highly nonlinear photonic crystal fiber (PCF) is presented. We propose a chromatic dispersion profile of a highly nonlinear PCF for flatly broadened SC generation around 1550nm. The proposed chromatic dispersion profile of the fiber which is a convex function of wavelengths has small normal group-velocity dispersion at the pump wavelength and the dispersion slope around which is flat. It is found that the fiber with such dispersion characteristics is suitable for generating a relatively flat SC. The initial chirp of the input pulse also has a significant effect on SC generation in photonic crystal fiber. A flatter and wider spectrum can be obtained by the pulse with appropriate positive initial chirp.
