Recently, optical pulses propagating through a photonic crystal fiber (PCF) of a special design were reported to yield a broad and flat supercontinuum (SC) spectrum around 1000nm because the fiber dispersion characteristics are of low dispersion around 1000nm. This study was undertaken to investigate spectral characteristics of SC pulses generated in two low dispersion PCFs which are a highly nonlinear PCF with group velocity dispersion (GVD) having an extremum value at zero dispersion and a lowly nonlinear PCF with GVD crossing zero dispersion. The influence of incident light pulse parameters (power, pulse width and chirp) and fiber length on SC spectra was also examined using those PCFs. Results show that highly nonlinear PCF with GVD distributions having an extremum value and zero dispersion around 1000nm is useful.
