Simulation investigation on supercontinuum generation and noise characteristics in the normal dispersion photonic crystal fiber with a flattened dispersion profile

Abstract:

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 o...
