Spatial solitons in photorefractive media

It is shown that photorefractive media can support a new type of spatial soliton, in which the diffraction is balanced by the self-scattering (two-wave mixing) of the beam spatial frequency components. This photorefractive soliton possesses some unique properties, such as independence of the absolut...

Zusammenfassung:It is shown that photorefractive media can support a new type of spatial soliton, in which the diffraction is balanced by the self-scattering (two-wave mixing) of the beam spatial frequency components. This photorefractive soliton possesses some unique properties, such as independence of the absolute light intensity, and can experience absorption (or gain) with no change in its transverse structure.
