ABSTRACT
We proposed and fabricated a nanofilm half-wave plate consisting of periodic arrays of orthogonally coupled slit-hole resonator structures in Au film. Experimental results reveal that 95.2% of energy of the incident linearly polarized light is converted to the perpendicular polarization direction after reflection from the nanostructure. The wave plate is single layer with only 180 nm thickness, which is much thinner than the operation wavelength. Our method can be expanded to other resonant structures or transmitted case.
