Outline of Final Research Achievements

The aim of this research is to produce rapid response and high sensitivity mid-infrared detectors by combining the field enhancement effect of an optical antenna and intersubband transitions in quantum wells. Toward this end, we have developed a technique to know the actual distribution of electric field components vertical to substrate surfaces of optical antennas in the depth direction by means of atomic layer deposition. Actually, its effectiveness was demonstrated by observing surface phonon polariton signals arising from SiC surface. Resonant Rayleigh scattering deteriorating photon absorption cross-section turned out to be negligible with optical antennas having relatively small enhancements as was the case in our experiments. Next, optical circular slot antennas were formed on AlGaAs/GaAs devices, and reflection spectra originating from intersubband transitions of GaAs quantum wells could be confirmed using a micro FT-IR.
