  We show the existence of nonlinear resonant states in a higher-order
nonlinear Schr\"odinger model that appertains to the wave propagation in
femtosecond fiber optics, under certain parametric regime. These nonlinear
resonant states are analytically illustrated in terms of Gaussian beams, Airy
beams, and periodic beams that resulted due to the presence of quadratic,
linear, and constant type of `smart' potentials, respectively, of the ensuing
model. Interestingly, the nonlinear chirp associated with each of these novel
resonant states can be efficiently controlled, by varying the self-steepening
term and self-frequency shift. Furthermore, we have conducted numerical
experiments corroborative of our analytical predictions.
