<title>Spatial and temporal soliton attractors in new polymeric waveguides</title>

Abstract

Dynamics of optical soliton attractor described by the generalized NSE model including the cubic and fifth-order nonlinearly and two-photon absorption is investigated. In the spectral range of positive GVD high-order nonlinear terms and two-photon absorption change dramatically the physical picture of high intensity pulse self-action. Instead of well known self-spreading and wave-breaking effects, the intense and short peak is formed on the broad pedestal. The most important results obtained in the numerical experiments are connected with soliton attractor forming in the negative GVD region. One can see that the strong nucleation of multi-soliton pulses creates the possibility to generate a new soliton-like high-energy pulse. An optical soliton attractor can be produced in a thin organic film waveguides by injecting a train of mode- locked laser pulses with the appropriate amplitudes and phases. The dynamics of soliton attractors forming in this case is strongly depends on the relative phases of interacting solitons. As follows from our computational modeling there exists the possibility to discover spatial and temporal soliton attractors in strongly nonlinear optical waveguides.
