      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 ...

      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)

      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
      Accés obert
      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 ...
