Stable structures with high topological charge in nonlinear photonic quasicrystals
arXiv:1003.2779 · doi:10.1103/PhysRevA.82.035802
Abstract
Stable vortices with topological charge of 3 and 4 are examined numerically and analytically in photonic quasicrystals created by interference of 5 as well as 8 beams, in the cases of cubic as well as saturable nonlinearities. These structures are experimentally realizable, including a prototypical example of a stable charge 4 vortex. Direct numerical simulations corroborate the analytical and numerical linear stability analysis predictions.
