| Abstract: | We report on theoretical investigations of beam control in one-dimensional tri-core photonic lattices(PLs).Linear splitting is illustrated in tri-core PLs;the effect of defect strength on the splitting is discussed in depth for single-wavelength light.We reveal that splitting disappears when the defect strength trends to zero,while reoccurring under nonlinearity.Multi-color splitting and active control are also proposed in such photonic structures. |
