TLDR
In this article, the concept of reconfigurable structures optically induced by mutually incoherent non-iffracting Bessel beams in Kerr-type nonlinear media was proposed and the switching properties of such structures can be tuned by varying the intensity of the Bessel beam.Abstract:
We put forward the concept of reconfigurable structures optically induced by mutually incoherent nondiffracting Bessel beams in Kerr-type nonlinear media. We address collinear couplers and X junctions and show how one can tune the switching properties of such structures by varying the intensity of the Bessel beams.read more

TL;DR: This work uses optical induction, the interference of two or more plane waves in a photosensitive material, to create a 2D photonic lattice in which the solitons form, paving the way for the realization of a variety of nonlinear localization phenomena inPhotonic lattices and crystals.

Discrete solitons and soliton-induced dislocations in partially coherent photonic lattices.
TL;DR: A clear transition from two-dimensional discrete diffraction to discrete solitons in such a partially coherent lattice is demonstrated and the nonlinear interaction process is associated with a host of new phenomena including lattice dislocation, lattice deformation, and creation of structures akin to optical polarons.

Rotary Solitons in Bessel Optical Lattices
TL;DR: It is shown that the cylindrical geometry of the lattice, with several concentric rings, affords unique soliton properties and dynamics and can be set into controlled rotation inside each ring, thus featuring novel types of in-ring and inter-ring soliton interactions.

Waveguides formed by quasi-steady-state photorefractive spatial solitons
TL;DR: The soliton induces a tapered waveguide that improves the coupling efficiency of light into the waveguiding structure and survives, either in the dark or when guiding the longerwavelength beam, for a long time after the soliton beam is turned off.
