    Turduev, M.; Botey Cumella, Muriel; Herrero Simon, Ramon; Kurt, H.; Staliunas, Kestutis; Giden, I. (Wiley-IEEE Press, 2015)
    Conference report
    Restricted access - publisher's policy
    We propose for the first time a simple realization of a two-dimensional Parity-Time symmetric hexagonal shaped photonic structure composed of honeycomb lattice. The structure has a symmetric periodic modulation of the ...
  • Asymmetric light transmission in PT-Symmetric microring resonators 

    Giden, I.; Dadashi, Kh.; Botey Cumella, Muriel; Herrero Simon, Ramon; Staliunas, Kestutis; Kurt, Hamza (2016-03-15)
    Article
    Restricted access - publisher's policy
    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 ...
  • Asymmetric transmission from a 2D PT-symmetric honeycomb nanostructure 

    Botey Cumella, Muriel; Herrero Simon, Ramon; Turduev, M.; Zhao, D.; Giden, I.; Kurt, H.; Staliunas, Kestutis (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference lecture
    Restricted access - publisher's policy
    We propose a simple realization of a 2-dimensonal (2D) PT-symmetric photonic structure: a honeycomb arrangement of alternating cylinders with gain or loss in a dielectric background. The structure provides a periodic ...
  • Mid-infrared T-shaped photonic crystal waveguide for optical refractive index sensing 

    Turduev, Mirbek; Giden, I.; Giden, Ibrahim H.; Babayigit, Ceren; Bor, Emre; Boztug, Çiçek; Kurt, Hamza; Staliunas, Kestutis (2017-06-01)
    Article
    Open Access
    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 ...
  • Two-dimensional complex parity-time-symmetric photonic structures 

    Turduev, M.; Botey Cumella, Muriel; Giden, I.; Herrero Simon, Ramon; Kurt, H.; Ozbay, E; Staliunas, Kestutis (2015-02-20)
    Article
    Open Access
    We propose a simple realistic two-dimensional complex parity-time-symmetric photonic structure that is described by a non-Hermitian potential but possesses real-valued eigenvalues. The concept is developed from basic ...
