Coupled plasmonic structures for sensing, energy and spectroscopy applications
(Bilkent University, 2015-08)Recent advances in nanofabrication and characterization methods have enabled the study of novel optical phenomena, thus boosting the research in nanophotonics and plasmonics. Metal nanostructures offer a route for the ... -
Infrared absorption spectroscopy of monolayers with thin film interference coatings
(Optical Society of America, 2017)We report high performance Infrared spectroscopy platforms based on interference coatings on metal using CaF2 dielectric films and Ge2Sb2Te5 (GST) phase-change films. IR vibrational bands of proteins and organic monolayers ... -
Perfectly absorbing ultra thin interference coatings for hydrogen sensing
(OSA - The Optical Society, 2016)Here we numerically demonstrate a straightforward method for optical detection of hydrogen gas by means of absorption reduction and colorimetric indication. A perfectly absorbing metal-insulator-metal (MIM) thin film ... -
Thermally tunable ultrasensitive infrared absorption spectroscopy platforms based on thin phase-change films
(American Chemical Society, 2016-11)The thermal tunability of the optical and electrical properties of phase-change materials has enabled the decades-old rewritable optical data storage and the recently commercialized phase-change memory devices. Recently, ...
