Abstract

Couplers Kudryashov Solitons
This paper is on couplers with optical metamaterials that are manufactured with polynomial nonlinear form that is also known as cubic–quintic–septic nonlinear form. Cubic–quartic solitons are recovered for such a form of waveguide with the enhanced Kudryashov’s approach. Bright and singular solitons are derived from this scheme for twin-core and multiple-core couplers.
