摘要：

The propagation of picosecond pulses in the normal dispersion photonic crystal fiber(PCF) with a flattened dispersion profile is numerically investigated.The characteristics of the amplitude and phase noise in the supercontinuum generation(SCG) are also analyzed through the coherent sliced supercontinuum(SC).The effects of self-phase modulation(SPM) and four-wave mixing(FWM) on broadening of the pulse spectrum are presented,and the best amplitude and phase noise performance with a specific fiber length is obtained.The SCG in the wavelength range of 1475 to 1625 nm has only fluctuation between ±1.5 dB,and both the amplitude and phase noise caused by the intensity noise of the input power is below 2.5% in the range of 1500 to 1600 nm.
