    • All-chalcogenide variable infrared filter 

      Kondakcı, H. Esat; Köyle, Özlem; Yaman, Mecit; Dana, Aykutlu; Bayındır, Mehmet (SPIE, 2009)
      We present the design, fabrication, characterization of spatially variable infrared filter and a demonstration of the filter as a simple infrared spectrometer. A varying photonic band gap filter which consists of thermally ...
    • Communication: Enhancement of dopant dependent x-ray photoelectron spectroscopy peak shifts of Si by surface photovoltage 

      Sezen, H.; Suzer, S. (2011)
      Binding energies measured by x-ray photoelectron spectroscopy (XPS) are influenced by doping, since electrons are transferred to (p-type) and from (n-type) samples when they are introduced into the spectrometer, or brought ...
    • Development of a rapid-scan fiber-integrated terahertz spectrometer 

      Keskin, H.; Altan, H.; Yavas, S.; Ilday, F. O.; Eken, K.; Sahin, A. B. (Springer New York LLC, 2014)
      Scientists in terahertz (THz) wave technologies have benefited from the recent developments in ultrafast laser technologies and RF technologies and applied these new gained techniques into characterizing a wide variety of ...
    • Photonic bandgap infrared spectrometer 

      Kondakci, H.E.; Yaman, M.; Dana, A.; Bayindir, M. (Optical Society of America, 2010)
      We propose and demonstrate an infrared (IR) absorption spectrometer, made with a spatially variable photonic bandgap (PBG) structure, a blackbody source, and a simple IR detector, to identify the IR molecular fingerprints ...
