Abstract

The paper studies soliton solutions in couplers with optical metamaterials that are governed by the lately proposed Kudryashov’s generalized form of power–law of refractive index. The low–count chromatic dispersion is also replenished with cubic–quartic dispersive effects. The couplers are of both kinds, namely twin–core couplers as well as multiple–core type. The auxiliary equation approach recovers a full spectrum of solitons that are exhibited with their necessary parameter restrictions.
