    • 2D anisotropic photonic crystals of hollow semiconductor nanorod with liquid crystals 

      Karaomerlioglu F.; Şimsek, Şevket; Mamedov, Amirullah M.; Özbay, Ekmel (2013)
      Photonic crystals (PCs) have many applications in order to control light-wave propagation. A novel type of two-dimensional anisotropic PC is investigated band gap and optical properties as a hollow semiconductor nanorod ...
    • Broadband circular polarizer based on high-contrast gratings 

      Mutlu, M.; Akosman, A. E.; Özbay, Ekmel (Optical Society of America, 2012-05-30)
      A circular polarizer, which is composed of periodic and two-dimensional dielectric high-contrast gratings, is designed theoretically such that a unity conversion efficiency is achieved at λ0 = 1.55 μm. The operation is ...
