In this study, a numerical method is introduced to obtain these solitons in different self-focusing / self-defocusing cubic-quintic media. Solitons obtained numerically by this spectral method are then validated by comparison with exact solutions. </span> <br> </p>}, number={1}, publisher={ISRES Publishing}
