In this talk, I will first introduce our recent progress on spatial shaping the near-field spatial patterns of surface plasmon vortices. Moreover, in all past studies, SP vortices were excited by far-field circularly polarized light. This means the functionality of the SP devices were merely converting the far-field spin angular momentum to orbital angular momentum in the near-field. In the second part, I will focus on the creation of surface plasmon vortex using non-angular momentum excitation. In the last part, the application of surface plasmon vortex for particle trapping and rotation will be presented.
