The Tunable Coupling between Metasurface and Molecular Vibration towards the Platform of Spectral Analysis
Nishijima Yoshiaki, Juodkazis Saulius
Bulletin of the Chemical Society of Japan 95 ( 9 ) 1318 - 1324 2022.9 [Reviewed]
DOI Web of Science CiNii Research
Language：English Publishing type：Research paper (scientific journal) Publisher：公益社団法人 日本化学会 Joint Work
<p>We have demonstrated the coupling of metasurface resonance with a molecular vibration from weak to strong. Metal-insulator-metal (MIM) metasurfaces using various polymers as the insulator layer (I-layer) were fabricated and characterised. The strength of coupling between MIM metasurface and molecular absorbance in the I-layer of organic nano-film depends on the dipole mode of the molecular vibration and the molecular number density. In the case of strong coupling, when Rabi-splitting is observed at the molecular absorption band, the coupling efficiency reaches several percent of the particular molecular vibration modes in the volume below nanodisks of the MIM metasurface.</p>

Control of Vibration-Metasurface Coupling at the Mid-Infrared Spectral Window for Inorganic Thermal Emitters
Nishijima Yoshiaki, Juodkazis Saulius
Bulletin of the Chemical Society of Japan 95 ( 9 ) 1411 - 1418 2022.9 [Reviewed]
DOI Web of Science CiNii Research
Language：English Publishing type：Research paper (scientific journal) Publisher：公益社団法人 日本化学会 Joint Work
<p>The coupling between light and molecular vibrational modes is dependent on the efficiency of molecular absorption. Here, we demonstrate a method to control the coupling between molecular mid-infrared absorption/emission in the chemical fingerprinting spectral window and a metasurface using SiO<sub>2</sub> as an absorber/emitter and CaF<sub>2</sub> as a spacer to optimize the strength of coupling. The use of inorganic dielectric I-spacers in metal–insulator–metal (MIM) metasurfaces opens applications in narrow-band emitters for a mid-infrared spectral window at elevated temperatures (>350 °C), where polymer/organic I-spacers degrade.</p>
