This article considers the twin-core couplers with Kudryashov's sextic power law of refractive index and perturbation terms. The extended F-expansion method is used to construct cubic-quartic solitons in optical metamaterials and other solutions. Bright soliton solutions, singular soliton solutions, periodic solutions, and combo periodic solutions are obtained. Moreover, some of the obtained solutions are represented graphically for physical illustration.
In this article, we consider the twin-core couplers with Kudryashov's sextic power law of refractive index and perturbation terms. The extended F-expansion method is implemented to construct cubic-quartic solitons in optical metamaterials and other solutions for the proposed model. Bright soliton solutions, singular soliton solutions, periodic solutions and combo periodic solutions are obtained. Moreover, for the physical illustration, some of the obtained solutions are represented graphically. (c) 2022 Elsevier Ltd. All rights reserved.
