Paper Abstract

A polarizer element with subwavelength nanostructured grating was fabricated by using focused iron beam. The gratings on the polarizer are variant spatially. By designing the distribution of the gratings, the polarizer can be used to convert circularly polarized light into radially polarized light. The operation wavelength of the element is 532nm, which has been confirmed by an experiment. Parameters associated with the polarized light converted by the polarizer were also measured in the experiment.
