Rotary dipole-mode solitons in Bessel optical lattices

We address Bessel optical lattices of radial symmetry imprinted in cubic Kerr-type nonlinear media and show that they support families of stable dipole-mode solitons featuring two out-of-phase light spots located in different lattice rings. We show that the radial symmetry of the Bessel lattices affords a variety of unique soliton dynamics including controlled radiation-free rotation of the dipole-mode solitons.Peer ReviewedPostprint (published version
