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.
