Surface topography and refractive index profile dictate the deterministic functionality of a lens. The polarity most lenses reported so far, that is, either positive (convex) or negative (concave), depends on curvatures interfaces. Here we experimentally demonstrate counter-intuitive dual-polarity flat lens based helicity-dependent phase discontinuities for circularly polarized light. Specifically, by controlling helicity input light, are interchangeable in one identical...
