We demonstrate spin-induced manipulation of surface-plasmon polariton (SPP) by exploiting the plasmonic spin Hall effect. By constructing metasurfaces with plasmonic atoms and varying spin-dependent geometric phase, we establish a holographic interface between an incident plane wave and the SPP on an optical chip. It allows us to gain spin-splitting and flexible control of the shapes and phases of the local SPP orbitals. Furthermore, a linearly polarized incident light with rotating polarization angle can be used to play a motion picture of the orbitals. These investigations provide a feasible route to many applications, including spin-enabled imaging, data storage and integrated optics.
