AI 中文摘要
我们证明了具有异号、异相空间调制自相位调制（SPM）和交叉相位调制（XPM）系数的双分量光子非线性晶格可以支持两种类型的光学矢量孤子（VSs），即基态和混合态。基态矢量孤子由两个类高斯分量组成，而混合态矢量孤子则结合了类高斯分量和偶极分量。我们研究了这两种类型矢量孤子的结构和稳定性。除传播常数较小值处的窄区间外，矢量孤子是稳定的。
英文摘要
We demonstrate that two-component photonic nonlinear lattices with opposite signs of the out-of-phase spatially modulated SPM and XPM coefficients can support two types of optical vector solitons (VSs), the fundamental and mixed ones. The fundamental VSs are composed of two Gaussian-like components, while the mixed ones combine Gaussian-like and dipole components. The structures and stability of both types of the VSs are investigated. The VSs are stable, except for narrow intervals at small values of the propagation constant.
