Localized vortex beams in anisotropic Lieb lattices
We address the issue of nonlinear modes in a two-dimensional waveguide array, spatially distributed in the Lieb lattice geometry, and modeled by a saturable nonlinear Schr odinger equation. In particular, we analyze the existence and stability of vortex-type solutions nding localized patterns with s...
