Optical soliton perturbation in magneto-optic waveguidesby extended (G'/G)-expansion method

One of the most viable applications of optical soliton sciences is in magneto-optic waveguides where an external magnetic field controls the effect of soliton clutter. This technological marvel has been implemented across the industry to enable a streamlined flow of soliton pulses across inter-continental distances. Therefore, it is imperative to study the governing model equation in magneto-optic waveguides and secure a soliton solution for looking into additional features such as conservation laws, numerical analysis and so on. This study obtains optical soliton solutions in magneto-optic waveguides with several perturbation terms. In addition to group-velocity dispersion, spatio-temporal dispersion term is taken into consideration. The analytical scheme employed to recover these solutions is extended (G'/G)−expansion approach. There are ten types of nonlinearities that are considered in this work. They are Kerr law, power law, quadratic-cubic law, parabolic law, dual-power law, log law, anti-cubic law, cubic-quintic-septic law and triple-power law nonlinearities and parabolic law with weak non-local nonlinearity. Bright, dark and singular soliton solutions are revealed. The constraint conditions for the existence of these solitons are also presented.
