Cubic-quartic optical solitons in couplers with optical metamaterials having Kudryashov’s sextic power law of arbitrary refractive index

Abstract

This article applies the addendum to Kudryashov’s method to secure the optical soliton solutions for the cubic–quartic (CQ) twin-core couplers and multiple-core couplers with optical metamaterials having Kudryashov’s sextic power law of arbitrary refractive index. The coupling with nearest neighbors and the coupling with all neighbors are introduced. The used method investigate the combo-bright–singular, bright and singular solitons solutions for the three models.
