We predict multiband vector plasmonic lattice solitons (PLSs) in metal-dielectric waveguide arrays, in both focusing and defocusing nonlinearities. Such vector solitons consist of two components originating from different transmission bands. By simulating the full nonlinear Maxwell's equations, we demonstrate the diffractionless propagation of vector PLSs and their discrete diffraction when only one component is present. Their subwavelength size characteristics and the influences of metallic losses are also studied.
我们预测了在金属-介质波导阵列中存在多带矢量等离子体格子孤子（PLS），其中包括聚焦和散焦两种非线性情况。这种矢量孤子由两个起源于不同传输带的分量组成。通过模拟完整的非线性麦克斯韦方程组，我们展示了矢量 PLS 的无衍射传播及其在仅存在一个分量时的离散衍射。我们还研究了它们的亚波长尺寸特性和金属损耗的影响。
