    • Beaming and localization of electromagnetic waves in periodic structures 

      Çağlayan, Hümeyra (Bilkent University, 2010)
      We want to manipulate light for several applications: microscopy, data storage, leds, lasers, modulators, sensor and solarcells to make our life healthier, easier or more comfortable. However, especially in small scales ...
    • Ferroelectric Based Photonic Crystal Cavity by Liquid Crystal Infiltration 

      Karaomerlioglu, F.; Simsek S.; Mamedov, A. M.; Ozbay, E. (Taylor & Francis, 2014)
      A novel type of two-dimensional photonic crystal is investigated for it optical properties as a core-shell-type ferroelectric nanorod infiltrated with nematic liquid crystals. Using the plane wave expansion method and ...
    • Hollow core photonic bandgap fibers for medical applications 

      Vural, Mert (Bilkent University, 2009)
      The design, fabrication and characterization of photonic band gap (PBG) based optical polymer fibers is discussed. Unlike conventional total internal reflection (TIR) fibers, used primarily in telecommunications, PBG ...
    • Organic semiconductor-based photonic crystals for solar cell arrays: band gap and optical properties 

      Karaomerlioglu, F.; Mamedov, A. M.; Ozbay, E. (Taylor & Francis, 2014)
      Photonic crystals (PCs) hold great potential for designing new optical devices because of the possibility of the manipulation of light with PCs. There has been an increase in research on tuning the optical properties of ...
    • Photonic crystal based multi-mode high-qcavity 

      Akosman, A.E.; Mutlu, M.; Kurt H.; Ozbay, E. (2011)
      An optical race-track has been investigated in order to obtain a multi resonant structure with high-Q factors. Photonic crystal based structure provides strong field confinement and scalability in the dimensions of the ...
    • Physics and applications of coupled-cavity structures in photonic crystals 

      Bayındır, Mehmet (Bilkent University, 2002)
      We proposed and demonstrated a new type of propagation mechanism for the electromagnetic waves in photonic band gap materials. Photons propagate through coupled cavities due to interaction between the highly localized ...
    • Physics and applications of photonic crystals 

      Temelkuran, Burak (Bilkent University, 2000)
      We first fabricated a dielectric based layer-by-layer photonic crystal, with a three-dimensional photonic band gap at microwave frequencies. We investigated the transmission, reflection and defect characteristics of the ...
