A simple scheme to steer optical beams is proposed. The basic idea is to impose a sinusoidal phase modulation on the optical beam and then propagate it in a nonlinear Kerr medium. Spatial phase modulation splits the input beam into multiple subbeams, while the nonlinear medium shapes a particular subbeam into a spatial soliton in such a way that most of the beam power appears in a narrow beam whose direction can be controlled by changing the modulation parameters. We present numerical results showing how spatial phase modulation can be used to alter the path of an optical beam propagating in a nonlinear Kerr medium.
提出了一种简单的光束控制方案。其基本思想是对光束施加正弦相位调制，然后使其在非线性克尔介质中传播。空间相位调制将输入光束分裂为多个子光束，而非线性介质则将特定子光束塑造为空间孤子，使得大部分光束功率集中在一束窄光束中，该窄光束的方向可通过改变调制参数来控制。我们给出了数值结果，展示了空间相位调制如何用于改变在非线性克尔介质中传播的光束路径。
