摘要：

This paper acquires cubic-quartic solitons in couplers with optical metamaterials that maintain quadratic-cubic nonlinear form. Two integration schemes, namely unified Riccati equation expansion scheme and an addendum to Kudryashov's approach have made this retrieval possible. Both multiple-core couplers as well as twin-core couplers are considered. A full spectrum of soliton solutions have emerged from these couple of algorithms.
