Femtosecond solitons in a dispersion flattened fiber with slow group-velocity

Research output: Contribution to journalConference articlepeer-review

Abstract

The slow group-velocity femtosecond autosolitons in a dispersion flattened fiber is investigated, of which third-order dispersion is nil and fourth-order dispersion is existent. For the femtosecond pulse with the half of normal group velocity, it is found that the analytic solutions of the bright soliton and dark soliton. The magnitude of the fourth-order dispersion parameter is related to the higher-order nonlinearity coefficient. The peak power and the period of the soliton are determined by the magnitude of the fourth-order dispersion parameter and the higher-order nonlinearity coefficient.
