我们从实验和数值上探索了维度在非互易能量交换支持的多(三个或更多)孤子融合中的作用。当存在一个没有破坏反转对称性的额外维度时，可以发现三个孤子融合成一个强波。在光折变晶体中的2+1维空间波中观察到了这一现象，其中孤子由空间饱和的类克尔自聚焦支持，融合由领先的非局域校正驱动，非局域校正是非线性拉曼效应的空间模拟。
We experimentally and numerically explore the role of dimensionality in multiple (three or more) soliton fusion supported by nonreciprocal energy exchange. Three-soliton fusion into an intense wave is found when an extra dimension, with no broken inversion symmetry, is involved. The phenomenon is observed for 2 + 1D spatial waves in photorefractive crystals, where solitons are supported by a spatially local saturated Kerr-like self-focusing and fusion is driven by the leading nonlocal correction, the spatial analog of the nonlinear Raman effect.
