Supercontinuum spectrum generation in dispersion-flatted fibers with concave dispersion profile

摘要

The supercontinuum (SC) spectrum generation is proposed in dispersion-flatted fibers with concave dispersion profile (DFF-CCDP). The effects of pulse characteristics and the fiber parameters on the SC spectrum characteristics are numerically investigated in the DFF-CCDP by using the split-step Fourier method. The characteristics of the SC spectrum become worse when the parameters are much smaller or greater. The parameters should be set according to the practical applications.
