We report on the stable self-focusing of light for various degrees of spatial coherence. Since the diffraction of a partially spatial coherent light beam is mainly governed by the transverse correlation width, its self-focusing is generally non-trivi

We study the existence and stability of multi-component spatial optical solitons in anisotropic nonlocal photorefractive media. For the case of three components, we find numerically the whole family of composite solitons with two perpendicular dipole

Stable dipole-mode vector solitons in photorefractive (PR) crystals are studied, both in numerical simulations and in experimental investigation. Numerically exact multi-humped solitary solutions to the propagation equations of two incoherently coupl

Self-bending of photorefractive solitons is caused by diffusion in photorefractive crystals and becomes an important effect when the beam size is in the range of the charge carriers diffusion length. In this paper we present an experimental and numer

We review the propagation and interaction behavior of spatial screening solitons generated in a photorefractive SBN crystal in order to exploit them for new perspectives in soliton-driven photonics. We report on the successful experimental generation

Chapter 8, on self-organized pattern formation in single-feedback systems, describes how the complexity of the material-light interaction is enhanced by allowing the system to feed the beam back into the nonlinear material. A single-mirror feedback s

In Chapter 9, multiple patterns and complex pattern competition, experimental results which reveal parameter regions of simultaneously stable patterns and of pattern competition are presented. The most surprising feature of a photorefractive single-f

Chapter 7 treats the case when a multimode waveguide is induced not by a single but several optical beams and vector solitons in a photorefractive medium can be constructed. In this case the participating modes are not guided in a passive way but int
