Interactions of chirped femtosecond soliton-like pulses

Abstract

This paper studies the interactions between two and more adjacent chirped soliton-like pulses, respectively. The results show that the pulses present strong interactions when the separations between them are smaller than a certain value, and their behaviour is very distinct under different conditions, such as a different number of pulses or different initial separations between them. Furthermore, we also study the suppression of these interactions and obtain very good effects by using different initial amplitude ratios.
