Terahertz waves are located in the frequency band between radio waves and light, and they are being considered for various applications as a light source. Generally, the use of light requires focusing; however, when a terahertz wave is irradiated ont

We report a study on three-dimensional transmission aperture of terahertz (THz) Bull's Eye structure. By applying three-dimensional aperture to a Bull's Eye structure, it is possible to achieve a higher intensity of electric field and localization of

We report transfer printing infrared light sources based on thermally excited Tamm plasmon polaritons. By using the transfer printing, it is possible to fabricate a laminated structure made by thick films more easily compared to the conventional devi

We report on a technique for resonant frequency tuning and miniaturization of a terahertz (THz) plasmonic structure. By applying solid immersion method to a non- concentric plasmonic structure, we achieved resonant frequency tuning of THz plasmon and

A detailed analysis of micro- and nanoantennas is crucial for enhancing the performance of photodetectors in the mid- and far-infrared (IR) region. In contrast to the rapid progress in IR detectors based on nanodevices, the local nanoscale properties

We report on a technique for tuning a resonant frequency and enhancing transmission of a bull's eye (BE) plasmonic antenna by forming dielectric materials on a sub-wavelength aperture. We observed that the use of the dielectric material shifted the p

We demonstrate a 32 × 32 path-independent-insertion-loss optical path switch that integrates 1024 thermooptic Mach-Zehnder switches and 961 intersections on a small, 11 × 25 mm2 die. The switch is fabricated on a 300-mm-diameter silicon-on-insulato

A Bull's eye (BE) plasmonic structure exhibits a powerful property of highly enhanced light transmission through a sub-wavelength aperture. However, the BE structure in the terahertz (THz) region exhibits the problems of a relatively low THz-field en
