    • Mid-infrared T-shaped photonic crystal waveguide for optical refractive index sensing 

      Turduev, Mirbek; Giden, Ibrahim H.; Babayigit, Ceren; Hayran, Zeki; Bor, Emre; Boztug, Cicek; Kurt, Hamza; Staliunas, Kestutis (Elsevier Science Sa, 2017-06)
      In this paper, we propose and design a new type of an integrated optical sensor that performs sensing in a wide wavelength range corresponding to mid-infrared (mid-IR) spectrum. By engineering the structural parameters of ...
    • Optical modulators and biochemical sensors based on low-symmetric nanophotonic structures with interferometric configurations 

      Yasa, Utku G.; Giden, Ibrahim H.; Kurt, Hamza (SPIE, 2018-02)
      Low-symmetric photonic crystals (PCs) have a high level of tunability in terms of their iso-frequency contours or refractive indices via angular orientations as well as spatial variations of unit cell elements. This ...
    • Strong electromagnetic field localization near the surface of hemicylindrical particles 

      Mahariq, Ibrahim; Giden, Ibrahim H.; Kurt, Hamza; Minin, Oleg V.; Minin, Igor V. (Springer, 2017-12)
      We theoretically study the forward and backward plane wave illuminations of hemicylindrical dielectric particles with different radii and refractive indices. Near field effects providing strong field enhancement and narrow ...
    • Tunable Metasurfaces with Liquid Crystals 

      Yilmaz, Nazmi; Bagci, Fehim T.; Ozdemir, Aytekin; Giden, Ibrahim H.; Ozer, Ahmet; Takashima, Yuzuru; Kurt, Hamza (SPIE, 2018-04)
      Intensive researches in the area of metasurfaces have provided a new insight to obtain flat and compact optical systems. In this letter, we numerically show that, highly efficient tunable beam steering effect in transmission ...
