Abstract(in English) Supercontinuum (SC) generation in normal group-disersion fibers is reported. Numerical calculations show that in the positive dispersion region, the SC spectrum broadens flatly as the input power increases, and that the dispersion slope limits the width of the broadened spectrum. According to the numerical calculations, we use the dispersion-flattened fiber having a small normal dispersion for SC generation, and a broad and flat SC spectrum is obtained when the intense power is launched into such fiber. We also find that the SC pulse width can be compressed to the Fourier-transform limit by using fibers with anomalous dispersion. This result shows that the SC pulse has a linear frequency chirp across the entire pulse width, and that the coherence property is maintained during the SC generation process.
