- (Contens №2 2020)
- ... Methodology. To assess the influence of the chirp on solitons interaction, our study is focused on fundamental solitons modelled by the famous Nonlinear Schrodinger Equation (NLSE) and simulated using Fast Fourier Transform. Firstly, we discuss the influence of the chirp by setting different values of group velocity dispersion (GVD) of one fundamental soliton. Secondly, we introduce the chirp on two fundamental solitons close enough to create Kerr-induced non-linearity and in the absence of GVD we study its impact on their interaction. Finally, we apply the chirp for two fundamental solitons with different phases, amplitudes and order of solitons to compare its impact on interactions in all cases possible. ...
