Cubic-quartic optical soliton perturbation in polarization-preserving fibers with complex Ginzburg-Landau equation having five nonlinear refractive index structures

In this research, we present a comprehensive coverage of soliton solutions to perturbed cubic-quartic (CQ) nonlinear complex Ginzburg-Landau (NLCGL) equation with five nonlinear laws to the refractive index. We specialize in studying the nonlinearity in the five different forms: Kerr law, parabolic law, polynomial law, quadratic-cubic law and parabolic non-local law. The integration scheme, namely the addendum to Kudryashov's approach has made this retrieval possible. For five laws nonlinearity, the analytical solutions are clearly constructed the combo-bright-singular, bright, dark and singular optical soliton solutions.

Automated summary

This research focuses on studying soliton solutions of perturbed CQ NLCGL equation with different nonlinear laws, and the integration scheme has made it possible to construct analytical solutions for combo-bright-singular, bright, dark, and singular optical solitons.
