数值研究了空间孤子通过具有纵向势垒的聚焦Kerr非线性光学晶格的隧穿行为，发现入射光的位置对空间孤子的隧穿行为有明显的影响，空间孤子在通过势垒时表现为压缩或分裂;晶格的横向调制频率和入射光的强度对空间孤子的隧穿能力有很大的影响。基于这些性质，我们提出了一种压缩孤子并将其分裂成稳定孪生光束的方案。所得结果在基于空间孤子的全光器件中具有很好的应用前景。
We numerically investigate the tunneling of spatial solitons through a focusing Kerr nonlinear optical lattice with longitudinal potential barrier, and find that the position of input beams apparently affects the tunneling behaviors of spatial solitons, which exhibit compression or splitting when passing through the barrier, and that the transverse modulation frequency of lattice and the intensity of input beams strongly affect the ability of tunneling. Based on these properties, we present a scheme for compressing soliton and splitting soliton into stable twin beams. The obtained results may have promising applications in all-optical devices based on spatial solitons.
