This work recovers cubic-quartic solitons in couplers with optical metamaterials, a specific form of optical waveguides. The couplers are with multiple core as well as twin-core. The multiple core couplers are studied with nearest neighbor coupling as well as all neighbor coupling. The dual-power nonlinear form of refractive index is taken into consideration. An addendum to the Kudryashov's algorithm is the integration scheme adopted here. Bright, singular and bright singular straddled solitons are derived. These solitons are presented along with their existence criteria.
