本文系统地分析了三维（3D）三次五次复金兹堡-朗道方程中固有涡度S = 0、1或2的稳定耗散涡旋在相对相位变化下的三种一般碰撞结果。第一类结果是涡旋合并为一个涡旋，其速度可以通过相对相位有效地控制。随着碰撞动量的增大，产生了一个额外的涡流，其速度也随着相对相的增大而增大。然而，在最大碰撞动量下，相对相位的变化不能改变第三种碰撞结果——准弹性相互作用。另外，产生额外涡的结果的动态范围随着立方增益的减小而减小。上述特性在基于光孤子相互作用的光开关和逻辑门中具有潜在的应用前景。
We present a systematic analysis for three generic collisional outcomes between stable dissipative vortices with intrinsic vorticity S = 0, 1, or 2 upon variation of relative phase in the three-dimensional (3D) cubic-quintic complex Ginzburg-Landau equation. The first type outcome is merger of the vortices into a single one, of which velocity can be effectively controlled by relative phase. With the increase of the collision momentum, the following is creation of an extra vortex, and its velocity also increases with growth of relative phase. However, at largest collision momentum, the variety of relative phase cannot change the third type collisional outcomes, quasielastic interaction. In addition, the dynamic range of the outcome of creating an extra vortex decreases with the reduction of cubic-gain. The above features have potential applications in optical switching and logic gates based on interaction of optical solitons.
