Abstract:Chalcogenide
phase-change materials (PCMs) exhibit low absorption
losses in the mid-infrared (MIR) region, which can be exploited for
MIR photonic applications. Furthermore, they show a significant change
in the optical properties with phase transformation. Surface-enhanced
infrared absorption spectroscopy using metamaterials has shown great
potential for detecting molecular fingerprint vibrations in the MIR
region. However, these metamaterials have a very narrow bandwidth,
limiting the range of molecular fing… Show more
