We demonstrate a technique for a single shot mapping of nonlinear phase shift profiles in spatial solitons that are formed during short pulse propagation through one-dimensional slab AlGaAs waveguides, in the presence of a focusing Kerr nonlinearity. The technique uses a single beam and relies on the introduction of a lithographically etched reflective planar mirror surface positioned in proximity to the beam's input position. Using this setup we demonstrate nonlinearity-induced sharp lateral phase variations for certain initial conditions, and creation of higher spatial harmonics when the beam is in close proximity to the mirror.
我们展示了一种技术，用于单次映射空间孤子中的非线性相移分布。这些空间孤子是在短脉冲通过一维平板AlGaAs波导传播过程中，在聚焦克尔非线性效应存在的情况下形成的。该技术使用单束光，并依赖于引入一个光刻蚀刻的反射平面镜表面，该表面位于光束输入位置附近。利用这种设置，我们展示了在某些初始条件下由非线性引起的尖锐横向相位变化，以及当光束靠近镜子时更高空间谐波的产生。
