In optics, the cubic-quintic nonlinear Schrödinger (CQNLS) equation models electromagnetic wave propagation in various optical media. Competing cubic and quintic nonlinearities will allow the existence of stable soliton solutions (see Göksel et al. (2015) ). 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.
