    • All-chalcogenide glass omnidirectional photonic band gap variable infrared filters 

      Kondakci, H. E.; Yaman, M.; Koylu, O.; Dana, A.; Bayındır, Mehmet (AIP Publishing, 2009)
      We report on the design, fabrication, and characterization of spatially variable infrared photonic band gap filter that consists of thermally evaporated, high refractive indexcontrast, amorphous chalcogenide glass multilayers. ...
    • Arrays of indefinitely long uniform nanowires and nanotubes 

      Yaman, M.; Khudiyev, T.; Ozgur E.; Kanik, M.; Aktas, O.; Ozgur, E. O.; Deniz, H.; Korkut, E.; Bayındır, Mehmet (Nature Publishing Group, 2011)
      Nanowires are arguably the most studied nanomaterial model to make functional devices and arrays. Although there is remarkable maturity in the chemical synthesis of complex nanowire structures, their integration and ...
    • Bioinspired optoelectronic nose with nanostructured wavelength-scalable hollow-core infrared fibers 

      Yildirim, A.; Vural, M.; Yaman, M.; Bayındır, Mehmet (Wiley, 2011)
      A digital photonic nose concept based on infrared absorption inside a hollow core infrared transmitting fiber array is presented. Wavelength-scalable photonic band gap fibers filter specific energy photons from a blackbody ...
    • High selectivity boolean olfaction using hollow-core wavelength-scalable Bragg fibers 

      Yaman, M.; Yildirim, A.; Kanik, M.; Cinkara, T. C.; Bayındır, Mehmet (American Chemical Society, 2012)
      A new odorant detection scheme, based on infrared absorption of volatile organics inside an optofluidic channel array, is discussed in terms of its selectivity. The sensor unit of the array is a hollow core Bragg fiber ...
    • Large and dynamical tuning of a chalcogenide Fabry-Perot cavity mode by temperature modulation 

      Yaman, M.; Kondakci, H. E.; Bayındır, Mehmet (Optical Society of America, 2010)
      Te-enriched chalcogenide glass Ge15As25Se15Te45 (GAST) is synthesized, thermo-optically characterized and used to fabricate a one dimensional photonic crystal cavity mode that is dynamically and reversibly tuned by temperature ...
    • Macroscopic assembly of indefinitely long and parallel nanowires into large area photodetection circuitry 

      Ozgur E.; Aktas, O.; Kanik, M.; Yaman, M.; Bayındır, Mehmet (American Chemical Society, 2012)
      Integration of nanowires into functional devices with high yields and good reliability turned out to be a lot more challenging and proved to be a critical issue obstructing the wide application of nanowire-based devices ...
    • Photonic bandgap infrared spectrometer 

      Kondakci, H.E.; Yaman, M.; Dana, A.; Bayındır, Mehmet (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 ...
    • Structural coloring in large scale core-shell nanowires 

      Khudiyev, T.; Ozgur E.; Yaman, M.; Bayındır, Mehmet (American Chemical Society, 2011)
      We demonstrated two complementary size-dependent structural coloring mechanisms, interference and scattering, in indefinitely long core-shell nanowire arrays. The unusual nanostructures are comprised of an amorphous ...
    • Template free preparation of nanoporous organically modified silica thin films on flexible substrates 

      Yildirim, A.; Budunoglu, H.; Yaman, M.; Güler, Mustafa O.; Bayındır, Mehmet (Royal Society of Chemistry, 2011)
      We report the preparation and characterization of nanoporous organically modified silica (ormosil) thin films at room temperature and neutral pH conditions from homogeneous methyl silsesquioxane (MSQ) gels. Universally ...
