© 2021 Elsevier GmbHThis work retrieves a complete spectrum of solitons to couplers with optical metamaterials that maintain parabolic nonlinear form. The unified Riccati equation expansion along with an addendum to Kudryashov's integration scheme has made this recovery of solitons possible. The solitons are displayed along with their respective existence criteria.
