Outline of Research at the Start

本課題では申請者らが開発してきた高出力の周波数可変テラヘルツ波光源とテラヘルツ帯の表面プラズモン共振器を基盤とする超高解像テラヘルツイメージングについて研究する。表面プラズモン共振器では表面電磁波と自由伝搬波の二重共鳴による透過増強と広帯域化について研究する。さらに高出力・周波数可変のテラヘルツ波を用いて構成した干渉計と透過増強型の表面プラズモン共振器を融合し、3次元の超高解像テラヘルツ画像計測法について研究する。

Outline of Final Research Achievements

Super-resolution three-dimensional terahertz imaging was studied using terahertz-wave resonators and optical coherence tomography (THz-OCT). We found continuous, broad-band operations of surface-plasmon resonators by introducing self-complementary log-periodic structures. We also found enhanced transmissions of doubly-resonant THz-wave resonators based on multimode Fabry-Perot resonances. Furthermore, we successfully obtained interferograms and their depth information by frequency-domain THz-OCT using a tunable THz-wave parametric source.

Academic Significance and Societal Importance of the Research Achievements

表面プラズモン共鳴型のテラヘルツ波共振器は従来単一デバイスでは単一周波数動作であったが、本課題において自己補対型対数周期アンテナの原理を導入し、連続広帯域動作が可能であることを明らかにした。このテラヘルツ帯プラスモニクスに関わる新しい学理は、次世代通信における広帯域テラヘルツ波処理回路にも適用できる社会的意義を有する。また、テラヘルツ波を用いた周波数ドメインOCTの実現は、高輝度な周波数可変テラヘルツ波光源の応用分野として3次元計測の分野を開拓する学術的意義をもつ。
