Abstract
The perturbed nonlinear Schrödinger equation (PNLSE), used to investigate the dynamics of wave propagation of light in nonlinear optical fibers and planar wave guides is considered in this article. The model is considered in the presence of full nonlinearity and perturbed terms. By using the state-of-the-art integration scheme, exp(− Φ(ξ))-expansion method, different structures of explicit solutions such as dark, singular, rational and periodic solitary wave solutions are celebrated. All the newly found solutions are discussed with their existence criteria.
