Abstract

We report on the first experimental observation of discrete vortex solitons in two-dimensional optically induced photonic lattices. We demonstrate strong stabilization of an optical vortex by the lattice in a self-focusing nonlinear medium and study the generation of the discrete vortices from a broad class of singular beams.

摘要

我们报道了二维光学诱导光子晶格中离散涡旋孤子的首次实验观测结果。我们展示了在自聚焦非线性介质中晶格对光学涡旋的强稳定作用，并研究了从一大类奇异光束中产生离散涡旋的情况。
