We study discrete vector solitons and vortices in two-dimensional photonic lattices with Kerr nonlinearity and demonstrate novel types of stable, incoherently coupled dipoles and vortex-soliton complexes that can be excited by Gaussian beams. We also discuss what we believe to be novel scenarios of the charge-flipping instability of incoherently coupled discrete vortices.
我们研究了具有克尔非线性的二维光子晶格中的离散矢量孤子和涡旋,并展示了新型的稳定、非相干耦合偶极子和涡旋-孤子复合体,它们可由高斯光束激发。我们还讨论了我们认为非相干耦合离散涡旋的电荷翻转不稳定性的新情况。
