We report on a numerical investigation of the effect of self-steepening on the dynamics of a passively modelocked fiber laser containing a long period fiber grating. The numerical model is based on the normalized complex Ginzburg-Landau equation and the nonlinear coupled mode equations of the grating. The nonlinear dynamics of the laser are observed through plotting the pulse energy against the linearly increasing gain so obtaining bifurcation diagrams. The inclusion of self-steepening was found to result in a temporal walk-off with no significant pulse width or energy alternations, while exhibiting different regions of period doubling bifurcation.
