摘要：
In this article, the extended F-expansion method is applied to secure cubic-quartic optical solitons for twin-core couplers with polynomial law of nonlinearity. Bright, singular, and bright- singular combo cubic-quartic solitons are derived. Also, periodic solutions, combo periodic solutions, exponential solutions and rational solutions are obtained. Moreover, for the physical illustration, some of the obtained solutions are represented graphically.
