    • Infrared absorption spectroscopy of monolayers with thin film interference coatings 

      Ayas, Sencer; Bakan, Gökhan; Ozgur, E.; Celebi, Kemal; Dana, Aykutlu (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 ...
    • Stress effects in prism coupling measurements of thin polymer films 

      Agan, S.; Ay, F.; Kocabas, A.; Aydinli, A. (Springer, 2005)
      Due to the increasingly important role of some polymers in optical waveguide technologies, precise measurement of their optical properties has become important. Typically, prism coupling to slab waveguides made of materials ...
    • Ultrathin phase-change coatings on metals for electrothermally tunable colors 

      Bakan, G.; Ayas S.; Saidzoda, T.; Celebi, K.; Dana, A. (American Institute of Physics Inc., 2016-08)
      Metal surfaces coated with ultrathin lossy dielectrics enable color generation through strong interferences in the visible spectrum. Using a phase-change thin film as the coating layer offers tuning the generated color by ...
