• 論文の詳細を見る

• We report on design and fabrication of a high-directivity plasmon-resonant terahertz emitter (PRE) having a 3D-integrated antenna complex. Previous PRE is based on a high electron mobility transistor (HEMT) and incorporates doubly interdigitated grating gates of broadband terahertz antennae converting non-radiative plasmons to radiative electromagnetic waves. Due to sub-wavelength aperture of practical grating dimensions, however, undesirable diffraction deteriorates the radiation directivity. A fine-patterned planar log-spiral antenna is dedicated on a separate Si substrate which is tightly coupled with the PRE in a 3D stack via micro-bump connections. The FDTD analysis demonstrates a better directivity by 〜77% than that for conventional in the terahertz range.
