We realize an absolute position control of drifting dissipative optical solitons by injecting an incoherent amplitude parameter gradient onto the nonlinear optical system. This allows for two-dimensional, arbitrary control patterns. The control of the soliton drift velocity is studied applying a periodic, hexagonally shaped modulation. The guiding of dissipative solitons by one- and two-dimensional parameter modulations is demonstrated. Furthermore, one-dimensional, line-shaped parameter modulations are designed to act as barriers for dissipative solitons, allowing implementations of position selectors for solitons. The interaction of dissipative optical solitons with barriers is studied for different barrier parameters.
通过将非相干振幅参数梯度注入到非线性光学系统中，我们实现了漂移耗散光学孤子的绝对位置控制。这允许实现二维任意控制模式。应用周期性六边形调制研究了孤子漂移速度的控制。演示了通过一维和二维参数调制对耗散孤子的引导。此外，一维线形参数调制被设计用作耗散孤子的势垒，从而实现孤子的位置选择器。针对不同的势垒参数，研究了耗散光学孤子与势垒的相互作用。
