Stable soliton complexes and azimuthal switching in modulated Bessel optical lattices
arXiv:physics/0410221 · doi:10.1103/PhysRevE.70.065602
Abstract
We address azimuthally modulated Bessel optical lattices imprinted in focusing cubic Kerr-type nonlinear media, and reveal that such lattices support different types of stable solitons, whose complexity increases with growth of lattice order. We reveal that the azimuthally modulated lattices cause single solitons launched tangentially to the guiding rings to jump along consecutive sites of the optical lattice. The position of the output channel can be varied by small changes of the launching angle.
