Abstract
This paper retrieves soliton solutions to couplers in optical metamaterials with triple-power law of nonlinear refractive index and is thus a sequel to previously reported results with polynomial law of nonlinear refractive index. The enhanced Kudryashov's scheme made this possible. Two kinds of couplers are addressed, namely twin-core and multiple-core. A full spectrum of soliton solutions are displayed.
