We have proposed using nano-antennas with superconducting detector to improve the response performance of infrared detectors. Dipole nano-antennas which have an NbN load resistance were fabricated to evaluate the antenna properties. By using EM simulation, the antenna length was set at 2400 nm for the operation around 7-μm-wavelength. The antennas were evaluated by using Fourier transform infrared spectroscopy. In an evaluation of spectral transmission characteristics, clear absorption caused by antenna effects was observed at around 1400 cm-1. The results of the simulation qualitatively agreed with the results of the experiment. The antenna effective area was also evaluated, and the area was estimated to be approximately 5.4 μm2 at 1420 cm-1. We have fabricated prototype of mid-infrared photo-detectors which were formed with 45 dipole-antennas with an NbN strip. The antennas were placed within an area of 20 × 20 μm2, and they were connected by bias line in series. By the irradiation of mid-infrared (λ=4.9 μm) light, the responses with high polarization dependencies caused by antenna effect were observed. |
