| Outline of Final Research Achievements |
We developed a basic technology for integrating pixels with different spectral responses on an infrared array sensor chip. Two types, an interference infrared absorber and plasmonic infrared absorber, were studied, and we have reached a conclusion that the plasmonic infrared absorber is superior from the viewpoint of productivity and performance. A problem of out-of-band sensitivity in the plasmonic infrared sensor has been solved by introducing a differential system with a reference pixel. We also showed that polarization-selective sensing is possible with an asymmetric plasmonics infrared absorber.
