提出了在具有压印贝塞尔光学晶格的立方非线性介质中存在局域项链孤子和局域环孤子。发现了新颖的项链孤子族，揭示了它们独特的性质，包括多稳态。我们证明了项链孤子和环孤子都可以存在于贝塞尔晶格的任何环上。它们是动态稳定的，只要晶格被调制得足够深。这些现象的发现为孤子的控制和操纵开辟了一条新的途径。
We put forward the existence of localized necklace solitons and ring solitons in a defocusing cubic nonlinear medium with an imprinted Bessel optical lattice. Novel families of necklace solitons are found and their unique properties, including multistable states are revealed. We show that both necklace solitons and ring solitons could reside on any ring of the Bessel lattices. They are dynamically stable provided that the lattice is modulated deep enough. The uncovered phenomena may open a new way for soliton control and manipulation.
