Abstract

With 4.28-km dispersion-flattened fiber (DFF), more than 254.9-nm 10-dB bandwidth on the right side of zero-dispersion wavelength and a 190.4-nm wide spectral region with the uniformity of within +-0.5 dB are obtained. While on the opposite side, 198.4-nm 10-dB bandwidth and 62.3-nm spectral region with the uniformity of within +-0.5 dB are obtained. More than 88 channels spaced at 2.52 nm on the long wavelength side are generated using Fabry-Perot (F-P) filter. The output supercontinuum (SC) characteristic is also analyzed by spectrum carving.
