| Outline of Final Research Achievements |
This study focused on realization of new kind of infrared sensor based on 3D photonic crystal. Ordinary infrared sensors based on semiconductors can produce infrared-sensitive photodetectors, such as photodiodes. However, this approach requires high purity semiconductors and their processing using advanced equipment in cleanroom and vacuum conditions. In this study, small infrared-sensitive photonic crystal structures were realized quickly in an ordinary laboratory environment. The sensors are optically readable, and therefore are free of electrical noise characteristic to traditional sensors. Their application may contribute to infrared sensing and imaging used in biological, medical, and security applications.
