摘　　要：本文数值研究了一种纵向呈周期性指数调制的克尔非线性光格子中空间孤子的控制和导向。结果表明,这种光格子能提供更大范围的孤子控制,通过合理设计光格子的参数如光格子的深度、横向调制频率、纵向调制周期以及输入波束的参数可以实现孤子的控制。In this paper, we numerically investigate the phenomena of the trapping and steering of spatial solitons in a Kerr-type nonlinear optical lattice with periodical longitudinal modulation that fades away and boosts up aLternately. The results show that such lattice can offer more scopes for soliton controls ; the soliton steering can be controlled very well by properly designing the lattice parameters such as Lattice depth, transverse modulation frequency and longitudinal modulation period, and adjusting the parameters of the initial input beam.
