Localized Structures in Dissipative Nonlinear Systems - Abstract
Biancalana, Fabio
The nonlinear light propagation in CS2-filled photonic crystal fibers is considered. Due to its slow reorientational nonlinearity, the highly non-instantaneous solitons propagating inside this liquid can be approximated, for pulse durations much shorter than the relaxation time, by the analytical solutions of a linear Schroedinger equation with a time-dependent potential proportional to the response function. The physical relevance of these novel solitary structures (which we have dubbed 'linearons') is discussed. We explore the dynamics of the self-frequency shift, the emission of resonant radiation and the collision of linearons, and we support our arguments by detailed numerical simulations.
