Abstract
We find families of analytical solutions for a recently proposed nonlinear partial differential equation describing pulse propagation in optical materials with polynomial law nonlinearity. By employing the Lie symmetry method, new explicit bright and dark soliton solutions are given. Furthermore, new doubly periodic solutions in terms of Jacobi elliptic functions are also obtained. The reported solutions have the advantage of being expressed in explicit forms in contrast with other works where they are presented in implicit forms.
