A novel chiral metasurface composed of a chiral arrangement of nanoslits is developed. Controllable and remarkably strong chiral responses are achieved by taking advantage of the coupling between localized and propagating surface plasmon modes. The finding provides an extra degree of freedom in manipulating chiral responses.
