| Outline of Final Research Achievements |
I conducted this study in order to experimentally demonstrate subwavelength optical devices that manipulate light waves at will within the one-wavelength path. Fundamental physical quantities of light waves are polarization vector and phase; therefore, if one is able to control the two quantities, it becomes possible to manipulate light waves at will. Thus, I worked on nanofabrication of subwavelength optical devices that control the polarization vector. Considering future practical application, the nanofabrication was done with UV nanoimprint lithography, resulting in success. The performance of the polarizer was experimentally found to exceed 15000 in the extinction ratio and was ranked at the high-end position, compared with existing conventional optical polarizers.
