Abstract: In this paper, we have designed and fabricated a four-zone binary subwavelength reflective micropolarizer. The $100\times100$-$\mu$m micropolarizer grating was synthesized by electron-beam lithography. FDTD-based numerical simulation and experimental characterization have shown the micropolarizer to be capable of transforming a linearly polarized incident Gaussian beam of wavelength $532$ nm into an azimuthally polarized beam.

Keywords: polarization, diffraction gratings, subwavelength structures.
