In this paper, one-dimensional (1D) nonlinear Schrodinger equations iut - uxx + mu + v |u|4u = 0, with Dirichlet boundary conditions are considered. It is proved that for all real parameters m, the above equation admits small-amplitude quasi-periodic solutions corresponding to b-dimensional invariant tori of an associated infinite-dimensional dynamical system. The proof is based on infinite-dimensional KAM theory, partial normal form, and scaling skills.
