摘要：
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.
