Reconfigurable soliton networks optically-induced by arrays of nondiffracting Bessel beams

Abstract

We address the propagation of solitons in reconfigurable two-dimensional networks induced optically by arrays of nondiffracting Bessel beams in Kerr-type nonlinear media. We show that broad soliton beams can move across networks having different topologies almost without radiation losses, opening new prospects for all-optical soliton manipulation. We also discuss various switching scenarios for solitons launched into multi-core directional couplers optically-induced by suitable arrays of Bessel beams.
