Abstract:

Using the variational method, the influence of the amplifier spontaneous emission (ASE) noise upon the optical pulse in dispersion management system is discussed, thus, the pulse phase variance, the central time variance and center frequency variation with distance is gained, and the influence of the amplifier spontaneous emission (ASE) noise is discussed in the densely dispersion managed soliton system and the larger negative average dispersion, the numerical simulation results show: the densely dispersion managed soliton system and the larger negative average dispersion can reduce the pulse impact of ASE noise.

Key words: nonlinear optics, dispersion-managed soliton, amplifier spontaneous emission noise, numerical simulation
