Jamie’s plasmonic circulator published in Nano Letters

A polarization-actuated circulator for surface plasmon polaritons (SPPs) is experimentally realized in the optical regime for the first time. We demonstrate circulations of SPPs can be actuated either by linearly polarized excitation or by spin angular momenta carried by circular polarizations. Experimentally, a wide optical operational bandwidth of ~ 100 nm is achieved.

A simple plasmonic nanostructure is designed to allow polarization‐sensitive directional steering of surface plasmon polaritons (SPPs). Based on crossed Babinet‐inverted nanoantennas, steering of SPPs in the full first quadrant with high sensitivity to the linear polarization of the monochromatic exciting source is numerically and experimentally demonstrated. The same device could also function as a polarization‐driven power‐splitter.
