Designed is dispersion-flattened photonic crystal fiber(PCF) with small normal dispersion for generating flat wideband supercontinuum(SC), and demonstrated is spectrally sliced pulse source which utilizes supercontinuum generated in dispersion-flattened photonic crystal fiber. The results show that the fiber characterized by flattened dispersion with small normal dispersion is suitable for flat wideband supercontinuum generation. In the process of spectral broadening, self-phase modulation plays a dominant role. By filtering the supercontinuum, multi-wavelength pulses can be obtained over a wide spectral range.
