Dynamics of Gaussian Optical Solitons by Collective Variables Method


Abstract: This work studies the classical optical solitons in the presence of perturbation terms that arise in various contexts of the propagation of solitons through optical fibers. The adiabatic parameter dynamics of these solitons are laid down by the aid of collective variables method. Employing the collective variable approach, femtosecond pulse propagation has been investigated in optical fibers using the higher order nonlinear Schroedinger equation (HONLSE). In order to view the pulse dynamics along the propagation distance, variation of different pulse parameters, called collective variables (CV), such as pulse amplitude, width, chirp, pulse center, and frequency have been investigated by numerically solving the set of ordinary equations obtained from collective variable approach.
