Outline of Final Research Achievements

(1)We fabricated metamaterial structure on the semiconductor substrate in THz region by photolithography technique. For example, wire grid structure acts as THz polarizer. We confirmed this phenomena by THz time-domain spectroscopy. (2)We fabricated poled polymer for THz generation by corona-poling technique. We chemically synthesized dye molecules named as LEMKE. We observed THz generation using LEMKE poled polymer film by THz time-domain spectroscopy. (3) Although we could not fabricated THz anisotropic metamaterial, we fabricated hyperbolic metamaterial in visible region as metal-dielectric multilayer structure. We confirmed broadband Purcell effect by time-resolved fluorescence measurement using several dye molecule on the metamaterial substrate.
