Multicolor vortex solitons in two-dimensional photonic lattices
arXiv:nlin/0412021 · doi:10.1103/PhysRevE.71.016616
Abstract
We report on the existence and stability of multicolor lattice vortex solitons constituted by coupled fundamental frequency and second-harmonic waves in optical lattices in quadratic nonlinear media. It is shown that the solitons are stable almost in the entire domain of their existence, and that the instability domain decreases with the increase of the lattice depth. We also show the generation of the solitons, and the feasibility of the concept of lattice soliton algebra.
