摘要：

A series of plasmonic devices are proposed to generate multi-patterned and two-dimensional optical lattices with or without helicity. Both the spin and orbital angular momentum of incident beam together with the excited polygonal plasmonic mode contribute to the formation of optical lattices due to the spin-orbit coupling. The impact of the mode property of incident beams on lattice pattern deforming is also discussed. Due to the compactness and flexible tunability, we believe that this work would facilitate the utilization of optical lattices in various on-chip applications.
