発明の名称 (英語) TERAHERTZ ELECTROMAGNETIC WAVE RADIATION ELEMENT AND ITS MANUFACTURING METHOD 実績あり
発明の概要(英語) The efficiency of conversion from a nonradiation two-dimensional electron plasmon wave into a radiation electromagnetic wave is improved and a wide-band characteristic is realized. A terahertz electromagnetic wave radiation element comprises a semiinsulating semiconductor bulk layer, a two-dimensional electron layer having a semiconductor heterojunction structure directly above the semiinsulating semiconductor bulk layer, source/drain electrodes electrically connected to two pieces opposed to the two-dimensional electron layer, a double gate electrode grating provided near the upper surface of the two-dimensional electron layer and capable of alternately setting two-different dc bias potentials parallel to the upper surface of the two-dimensional electron layer, and a transparent metal mirror provided in contact with the lower surface of the semiconductor bulk layer, formed into a film shape, functioning as a reflecting mirror in the terahertz band, and transparent to the light wave band. Two light waves are made to enter through the lower surface of the transparent metal mirror, two different dc bias potentials are alternately applied to the double gate electrode grating, and the electron density in the two-dimensional electron layer is periodically modulated in accordance with the configuration of the double gate electrode grating.
