Development of Mid-infrared Plasmonics and Thier Sensor Applicatons

Abstract

In recent years, research on mid-infrared plasmonics, which enables qualitative and quantitative analyses of substances by vibration spectroscopy, has been studied all over the world. We have developed new plasmonic materials for constructing a breakthrough mid-infrared sensor, such as new alloy materials based on dielectric permittivity analysis for plasmonic materials, surface enhanced infrared absorption (SEIRA) with a transmissive plasmon material, metal hole array (MHA), and metal-insulator-metal nanostructure (MIM) type meta-surface structure for the mid-infrared light source/detector. This comprehensive paper summarizes the global trends of these plasmonic materials and our researches.
