We study experimentally the interaction of mutually incoherent bright spatial solitons in dye-doped nematic liquid crystals (LCs). The dye-induced light absorption results in a complex nonlinear optical response of the LC having spatially nonlocal focusing and defocusing contributions. The competition between both nonlinearities leads to the separation-dependent soliton interaction with repulsion of distant and attraction of closely placed solitons.
我们通过实验研究了互不相干的亮空间孤子在染料掺杂向列相液晶中的相互作用。染料引起的光吸收导致液晶具有空间非局域聚焦和散焦贡献的复杂非线性光学响应。两种非线性的竞争导致了与分离相关的孤子相互作用，即远距离孤子相斥，近距离孤子相吸。
