Slow-light spatial solitons.
We numerically and experimentally report the observation of slow-light spatial solitons in a Kerr medium owing to light amplification by stimulated Raman scattering. This was achieved in a CS2 nonlinear planar waveguide that possesses both a strong self-focusing nonlinearity to generate the spatial Raman soliton and a Raman susceptibility sharp enough to induce the slow-light process simultaneo...

متن کاملGuiding Light for Future Technologies SPATIAL OPTICAL SOLITONS
1047-6938/02/02/0059/5-$0015.00 © Optical Society of America One of the goals of modern nonlinear optics is the development of the ultimate fast, all-optical device in which light can be used to control light. The unique possibilities of reconfigurable circuits created in nonlinear bulk media without any fabricated optical waveguide can be achieved by employing the fundamental concept of light ...
متن کاملSpatial solitons and light-induced instabilities in colloidal media.
We study nonlinear light propagation in colloidal nanosuspensions. We introduce a novel model for the nonlinear response of colloids which describes consistently the system in the regimes of low and high light intensities and low/large concentrations of colloidal particles. We employ this model to study the light-induced instabilities and demonstrate the formation of stable spatial solitons as ...
متن کاملSpatial solitons and instabilities in two-colour Helmholtz light fields
Two-colour optical beams comprise a pair of light waves at two well-separated temporal frequencies, and which are coupled through system nonlinearity (e.g., the Kerr-type response in the host material of a planar waveguide) [1]. In addition to their fundamental theoretical interest, these types of two-colour configurations have huge potential for future photonic device applications (e.g., multi...
