    • 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 ...
    • Direct imaging of localized surface plasmon polaritons 

      Balci, S.; Karademir, E.; Kocabas, C.; Aydinli, A. (Optical Society of America, 2011)
      In this Letter, we report on dark field imaging of localized surface plasmon polaritons (SPPs) in plasmonic waveguiding bands formed by plasmonic coupled cavities. We image the light scattered from SPPs in the plasmonic ...
    • Grating based plasmonic band gap cavities 

      Senlik, S.S.; Kocabas, A.; Aydinli, A. (Optical Society of American (OSA), 2009)
      We report on a comparative study of grating based plasmonic band gap cavities. Numerically, we calculate the quality factors of the cavities based on three types of grating surfaces; uniform, biharmonic and Moiré surfaces. ...
    • 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 ...
    • Physics and applications of defect structures in photonic crystals 

      Özbay, Ekmel; Bayındır, Mehmet (Springer, 2003)
      We propose and demonstrate a new type of propagation mechanism for electromagnetic waves in photonic band gap materials. Photons propagate through coupled cavities due to interaction between the highly localized neighboring ...
