Solitons

Research Project

bris

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 3D circuits created in nonlinear bulk media without any fabricated optical waveguide can be achieved by employing the fundamental concept of light guiding light, based on the propagation of spatial optical solitons.
Spatial solitons, or self-trapped, self-guided light beams that do not spread because of diffraction when they propagate in a nonlinear bulk medium, are considered information-carrying units, and the process of all-optical switching can be associated with the evolution of different types of spatial optical solitons and the interactions between them.
Our research activities on spatial solitons are twofold : fundamentals and applications. A first project aims at studying and understanding spatial vector solitons and their stability in pure Kerr media. The second main part deals with the photorefractive soliton in Lithium Niobate and their potential applications to integrated optics and reconfigurable 3-D optical circuitry.
