Abstract: Abstract of poster: A higher order nonlinear integro-differential equation of the Schroedinger type modelling the evolution of finite amplitude wavepackets in the presence of optical amplification and finite material - and polarization time responses is analyzed with respect to the dynamical evolution of localized solutions. Nonexistence of localized travelling and stationarywave solutions is pointed out for certain parameterregimes. The linear stage of modulational instability of plane wave is studied and it is shown that the finite timeresponses produce finite bandwidth instabilities.
