ABSTRACT

The originality of this work is to specify in detail the effect of each value of the phase on the solitonic interactions of both fundamental and higher order solitons as well as its use in the separation of adjacent solitons, and in suppressing interactions with different amplitudes. Firstly, we carry out a general study of the effect of the phase on two adjacent solitons in order to find the good value that is able to separate them during their propagation. Secondly, our study is focalized on the distinction of the two different cases of the interactions for repulsive and attractive cases according to the phase value. Then, we study the possibility of separating a group of solitons by injecting solitons with different amplitudes. Finally, the effect of the phase on the fission of the higher order solitons is analysed.
