  • Numerical solutions to the soliton nonliner Schrodinger (NLS) equation of higher-order dispersion effect find the third-order dispersion effect causing the soliton pulse seat to oscillate on a single side and the fourth-order effect causing it to oscillate on both sides,which result in the neighboring optical pulses overlapping and the shapes of the optical pulses distorting.The secondary pulses are evoked between the pair of optical soliton,therefore,cause systematic error code.We suggest that the third-order dispersion should be compensated on purpose in order to reduce systematic error code.

Abstract: Numerical solutions to the soliton nonliner Schrodinger (NLS) equation of higher-order dispersion effect find the third-order dispersion effect causing the soliton pulse seat to oscillate on a single side and the fourth-order effect causing it to oscillate on both sides,which result in the neighboring optical pulses overlapping and the shapes of the optical pulses distorting.The secondary pulses are evoked between the pair of optical soliton,therefore,cause systematic error code.We suggest that the third-order dispersion should be compensated on purpose in order to reduce systematic error code.
