We demonstrate here that control of local optical field near a single non-chiral gold nano-rectangle irradiated with linearly polarized light is possible from linearly polarized to nearly pure left- or right-handed circular polarization, by adjusting the angle of the incident polarization relative to the rectangle.

We experimentally demonstrate that non-chiral plasmonic nanostructured materials interacting with linearly polarized
(non-chiral) light generate elliptically polarized (chiral) optical near-fields in local nano spaces around the materials.
