| Outline of Final Research Achievements |
We have proposed using nano-antennas with superconducting detector to improve the response performance of infrared detectors. For the construction of design guide of infrared antenna, nano-slot antennas were fabricated and evaluated. Through measurements of the spectral reflectance characteristics, clear absorptions caused by the antenna properties were observed in the infrared region. By considering the abnormal skin effect, we showed that it is possible to design antennas in the infrared region by using an electromagnetic simulator. The effective area of the antenna was also evaluated and was found to be approximately 3.5 μm2 at 54 THz.
We have fabricated prototype of mid-infrared photo-detectors which were formed with 45 dipole-antennas with an NbN strip. By the irradiation of mid-infrared (λ=4.9 μm) light, the responses with high polarization dependencies caused by antenna effect were observed.
