    • Adaptive Graded Index Photonic Crystal Lens Design via Nematic Liquid Crystals 

      Giden, Ibrahim Halil; Eti, Neslihan; Rezaei, Behrooz; Kurt, Hamza (IEEE-Inst Electrical Electronics Engineers Inc, 2016-10)
      An adaptive graded index photonic crystal (GRIN PC) lens system is designed by using liquid crystal (LC) infiltration. LCs have the property to change their refractive indices when an external voltage is applied. This ...
    • Asymmetric Light Transmission in PT-Symmetric Microring Resonators 

      Giden, Ibrahim Halil; Dadashi, Khalil; Botey, Muriel; Herrero, Ramon; Staliunas, Kestutis; Kurt, Hamza (IEEE-Inst Electrical Electronics Engineers Inc, 2016)
      We propose a new type of add-drop microring resonator made of gain and loss materials. Microring resonators are compact, narrow band, and optical channel dropping filters. In such linear systems, light transmission to ...
    • Enhanced super-prism effect with self-collimation by dispersion management in C-1 symmetric photonic crystals 

      Gumus, Melike; Giden, Ibrahim Halil; Kurt, Hamza (SPIE, 2018-02)
      Photonic crystals ( PhCs) are artificial wavelength-scale periodic structures that enable the manipulation of light propagation and possess intriguing dispersive characteristics such as negative refraction, self-collimation, ...
    • High Extinction Ratio Polarization Beam Splitter Design by Low-Symmetric Photonic Crystals 

      Yasa, Utku Gorkem; Turduev, Mirbek; Giden, Ibrahim Halil; Kurt, Hamza (IEEE-Inst Electrical Electronics Engineers Inc, 2017-05-01)
      A novel concept of polarization beam splitting with high polarization extinction ratio is proposed based on the polarization sensitive self-collimation feature of symmetry reduced photonic crystals. The idea utilizes ...
