Rotary dipole-mode solitons in Bessel optical lattices
We address Bessel photonic 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 afford a variety of unique soliton dynamics …
