Our paper studies the optical solitons of the fiber Bragg gratings with cubic–quartic dispersive reflectivity having parabolic law and parabolic-nonlocal-combo law. By using the improved modified extended tanh-function method, we can obtain bright, dark and singular soliton solutions. Also, we can get different types of solutions, namely periodic wave solutions, hyperbolic type solutions, singular periodic wave solutions, exponential solutions and Weierstrass elliptic doubly periodic solutions. Furthermore, graphic representation for some obtained solutions is given for more illustrations.
