Abstract

Internal modes and internal oscillation of necklace solitons in Bessel photonic lattices imprinted in self- defocusing and self-focusing materials are investigated. Under the same parameters, necklace solitons in self- focusing material possess larger power than that of self-defocusing material, and the stability of solitons in defocusing material is better than in focusing material. It is shown that the internal modes have both real and imaginary parts in such cases, differing from the one-dimensional case. While white noise gives rise to jitter of the intensity of stable necklace solitons, the stable solitons perform long-distance and quasi-periodic oscillation of intensity and shape under the perturbation of internal modes, and the solitons in self-defocusing material experience larger oscillation amplitude than that in self-focusing material.
