Pulse Compression And Pedestal Suppression For The High-Order Solitons

Abstract

A pulse compression and pedestal suppression method for high-order solitons is presented in this paper. With the existing analytic solutions, the second- and third-order solitons are compressed, and the optimum lengths for them are obtained. Without the soliton broadening, the pedestals of the solitons from different outputs can be suppressed with the choices of corresponding parameters. Unlike other pedestal suppression methods, the energy of the pedestal is transferred to the peak of the soliton, and the output intensity of the high-order compressed solitons increases during the pedestal suppression. As the soliton order increases, results show that the optimum length for the pedestal suppression increases, and the pulse width decreases.
