Abstract
The optical solitons are extracted with Chen–Lee–Liu (CLL) equation that is considered with group velocity dispersion. The CLL equation describes the propagation of optical pulses in monomode fibers. In this article, the variety of solitons like dark, singular, dark-singular, bright-dark and periodic solutions are obtained by the mean of Fan-extended sub equation method under different constraint conditions. Moreover, for showing the physical interpretation of some recovered solutions, we also plot 3D maps by using the suitable values of involved parameters in solutions. The performance of the used method shows the adequate, validity and ability for implementation to many other nonlinear models.
