    • Asymmetric light transmission by using 2D PT-symmetric photonic nanostructure 

      Turduev, M.; Botey, M.; Herrero, R.; Giden, I.; Kurt, Hamza; Staliunas, K. (Institute of Electrical and Electronics Engineers Inc., 2014-12)
      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 transmission from a 2D PT-symmetric honeycomb nanostructure 

      Botey, M.; Herrero, R.; Turduev, M.; Zhao, D.; Giden, I.; Kurt, Hamza; Staliunas, K. (IEEE Computer Society, 2014)
      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 ...
    • Chiral modes in 2D PT-symmetric nanostructures 

      Botey, M.; Herrero, R.; Turduev, M.; Giden, I.; Kurt, Hamza; Staliunas, K. (Springer Science and Business Media, LLC, 2016)
      We propose a 2-dimensonal PT-symmetric photonic honeycomb structure that supports chiral Block-likemodes being its excitation input and frequency dependent. We show that while the fundamental resonant frequency excites the ...
    • Nonreciprocal light transmission in gain-loss modulated Micro ring resonators 

      Giden, I.H.; Dadashi, K.; Botey, M.; Herrero, R.; Staliunas, K.; Kurt, Hamza (IEEE Computer Society, 2015)
      We propose a new type of add-drop Micro ring resonator that is made up of gain and loss materials. In all-dielectric linear systems, light transmission is reciprocal: A symmetric transmission spectrum is observed when an ...
    • PT-vector fields 

      Ahmed, Waqas Waseem; Herrero, R.; Botey, M.; Hayran, Z.; Kurt, Hamza; Staliunas, K. (SPIE, 2018)
      Non-Hermitian potentials, as known since a decade, can favor unidirectionality of the flows in one and two-dimensional systems. Inspired by such counterintuitive property of non-Hermitian potential, we propose a novel ...
    • Self-collimation in 2D complex and PT-symmetric media 

      Botey, M.; Turduev, M.; Kurt, Hamza; Herrero, R.; Staliunas, K. (IEEE Computer Society, 2015-08)
      We study propagation light beams in 2D photonic periodic nanostructures with both index and gain/loss modulations. We determine the conditions for complex periodic media with in-phase gain and index modulations to support ...
    • Two-dimensional complex parity-time-symmetric photonic structures 

      Turduev, M.;  Botey, M.;  Giden, I.; Herrero, R.; Kurt, Hamza;  Ozbay, E.;  Staliunas, K. (American Physical Society, 2015-02)
      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 ...
