    • 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 ...
    • Artificial olfaction inside nanostructured infrared fiber arrays 

      Yaman, Mecit; Yıldırım, Adem; Bayındır, Mehmet (IEEE, 2011)
      Nanostructured hollow core fibers are used to demonstrate a new infrared absorption based artificial nose. The sensor unit of the array is a hollow core Bragg fiber that selectively guides incident blackbody radiation and ...
    • Bio-insprired optoelectronic digital nose for breath analysis 

      Bayındır, Mehmet; Yıldırım, Adem; Yaman, Mecit; Vural, Mert (2011)
      A novel electronic nose device is presented that can be used in disease diagnostics by exhaled breath analysis. Exhaled breath contains more than a thousand organic compounds that can be analysed to insect various diseases ...
    • Macroscopic photoconductive nanowire arrays 

      Bayındır, Mehmet; Yaman, Mecit; Özgür, Erol; Aktaş, Ozan; Khudiyev, Tural; Kanık, Mehmet; Deniz, Hakan (IEEE, 2011)
      A novel high-throughput fabrication technique to produce polymer embedded functional chalcogenide nanowire arrays is demonstrated. Indefinitely-long selenium nanowire arrays are obtained and their size dependent photoconductivity ...
    • Nano-structured organically modified silica thin films for functional surfaces 

      Bayındır, Mehmet; Yıldırım, Adem; Budunoglu, Hülya; Yaman, Mecit; Deniz, Hakan; Guler, Mustafa O. (2011)
      We report a template-free sol-gel method for preparation of nanoporous ormosil thin films at ambient conditions. The thin films are coated to the surfaces by using colloidal suspensions of ormosil gels. Gels are synthesized ...
