We numerically and experimentally show the existence of multicolor vector spatial solitons in a Kerr planar waveguide through the combined effects of cross-phase modulation, four-wave mixing, and stimulated Raman scattering. Mutual spatial guiding of the Raman-Stokes, anti-Stokes, and pump waves is achieved in the high-conversion regime mainly by cross-phase modulation and phase-matched four-wave mixing induced by a power imbalance between Stokes and anti-Stokes components, leading to the generation of a clear-cut sech-shape three-frequency spatial soliton.
我们通过交叉相位调制、四波混频和受激拉曼散射的联合效应，在数值和实验上证明了克尔平面波导中多色矢量空间孤子的存在。在高转换 regime 中，拉曼 - 斯托克斯波、反斯托克斯波和泵浦波的相互空间引导主要通过交叉相位调制以及由斯托克斯和反斯托克斯分量之间的功率不平衡引起的相位匹配四波混频来实现，从而导致产生清晰的 sech 形三频空间孤子。
