    • 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. ...
    • Two-dimensional ferroelectric photonic crystals: Optics and band structure 

      Simsek S.; Mamedov, A. M.; Özbay, Ekmel (Taylor & Francis Inc., 2013-09-20)
      In this report we present an investigation of the optical properties and band structure calculations for the photonic structures based on the functional materials- ferroelectrics. A theoretical approach to the optical ...
    • Vortex lattice of a Bose-Einstein condensate as a photonic band gap material 

      Taşgin, M. E.; Müstecaplioǧlu, Ö. E.; Oktel, M. Ö. (IOP Institute of Physics Publishing, 2009)
      Photonic crystal behavior of a rotating Bose-Einstein condensate with a triangular vortex lattice is reviewed and a scheme for getting much wider band gaps is proposed. It is shown that photonic band gaps can be widened ...
