Abstract
he effects of third-order dispersion (TOD) and intrapulse Raman scattering (IRS) on the erupting solitons
of the complex cubic-quintic Ginzburg-Landau equation are investigated by direct numerical simulations
and linear stability analysis. Our results indicate that positive TOD eliminates eruptions on the leading
edge of the soliton, whereas negative TOD cancels them on the other side. Moreover, the combined action
of TOD and IRS is in certain cases able to eliminate explosions on both sides of the soliton, at much lower
IRS values than with IRS alone. The profiles of the stationary solutions are increasingly asymmetric with
TOD, and their velocity varies almost linearly with IRS.n
