摘　　要：采用数值法研究了在具有光致异构非线性的聚合物中平行传播的光学空间孤子对(信号光)被另一束垂直入射光调控的情况.调节调控光和信号光的初始相位差、调控光入射位置等可以使信号光孤子产生合成、分开等现象,对此给出了物理解释.这种相互作用的空间光孤子被垂直光调控的现象可望应用于光合成、光互联、光波导等方面.In photoisomerization polymer, the perpendicular optical control of the optical spatial soliton interaction is simulated by numerical method. Under control, the properties of two interacting solitons are damaged, the signal beam can give birth to phenomena such as the two beams to join together, or to detach and so on. We also give a physical explanation of the phenomena, that they are determined by the difference in the initiatial phases of the beams, the incident position of control-beam and so on. The effect of perpendicular optical control of interaction solitons can be applied to optical interlinkage, optical waveguide and so on.
