| Outline of Final Research Achievements |
A mass transport driving force in an azo-polymer is mostly driven from a bright fringe toward a dark fringe along the polarization direction of the light. Thus, a chiral surface relief formation in the azo-polymer film is generally inhibited by the irradiation of linearly or circularly polarized light. We discovered that a novel chiral structured surface relief with a micro-scale height can be established in an azo-polymer film by irradiating circularly polarized optical vortex with a total angular momentum of J=2. The temporal evolution of the chiral surface relief formation in the azo-polymer film was also observed. Such chiral surface reliefs will open the door to new materials sciences, such as planar chiral metamaterials, plasmonic holograms, and identification of chiral chemical composites.
