摘要：
This article studies the dynamics of optical solitons in cubic-quintic nonlinear Schrodinger model that describes the propagation of femtosecond light pulses in optical fibers. The model is considered with self-steepening and self-frequency shift. As a result, the dark and singular optical solitons are extracted using (G'/G)-expansion scheme. Additionally, the constraint conditions for the existence of these solutions are also listed.
