Complex Optical Waveguiding Structures Induced By Bessel Beams

The propagation and interaction of unconventional Airy beams in nonlinear media permits the creation of multiple photo-induced waveguiding structures which are interesting for the development of all-optical interconnects [1] , [2] . Such complex light-induced structures, different from those induced by Gaussian beams, result from the unique profiles and peculiar characteristics of Airy beam (diffraction-free, self-healing). Bessel beams share similar features with Airy beams and have been studied in the past and recent years for example in a self-focusing nonlinear medium [3] , [4] where soliton-like, breathing and self-trapping properties have been observed. However, the studies are limited only to a single Bessel beam in a quadratic electro-optic response, and nonlinear interactions of Bessel beams is not studied.
