Outline of Final Research Achievements

Vectorial vortex beam, which has spatial singularlity in polarization and　phase,　has　been　studied　several　applications　such　as　super　resolution　microscope,　laser processing, optical communications, and optical storages, due to their unique optical characterization. In general, it is difficult to achromatically generate and control the vectorial vortex beams, because such beams has strongly depended on the wavelength. We demonstrate to control achromatic vectorial vortex beams by use of internal Fresnel reflections in near and middle infrared spectral regions and to determine the arbitrary polarization states by use of vectorial vortex analysis.
