Optical solitons to the cubic quartic Bragg gratings with anti-cubic new

ABSTR A C T In this study, we introduce a new simple integration technique to extract optical solitons for the cubic quartic Bragg-gratings having anti-cubic nonlinear form. The extracted solitons are in the form of bright, dark, singular soliton solutions. Beside these solitons, bright-dark hybrid soliton solutions are also retrieved. The obtained results demonstrate that our method is extremely simple and very effective for seeking exact solutions and then extracting optical solitons for the governing model. Appropriate constraints emerged of the obtained solitons to guarantee their existence.
