    • Angular filtering by Bragg photonic microstructures fabricated by physical vapour deposition 

      Grineviciute, Lina; Babayigit, Ceren; Gailevicius, Darius; Bor, Emre; Turduev, Mirbek; Purlys, Vytautas; Tolenis, Tomas; Kurt, Hamza; Staliunas, Kestutis (2019-07-01)
      Article
      Open Access
      We propose and experimentally demonstrate spatial filtering by photonic crystals in a Bragg configuration. Compared to the Laue configuration, where spatial filtering was already demonstrated before, the Bragg configuration ...

    • Asymmetric light transmission effect based on an evolutionary optimized semi-Dirac cone dispersion photonic structure 

      Bor, Emre; Turduev, Mirbek; Yasa, Utku Görkem; Kurt, Hamza; Staliunas, Kestutis (American Physical Society (APS), 2018-12-10)
      Article
      Open Access
      In this paper, we present the numerical and experimental demonstration of asymmetric light transmission by a compact photonic crystal (PC) structure, which sustains semi-Dirac cone dispersion. The semi-Dirac point is ...

    • Directional invisibility by genetic optimization 

      Bor, Emre; Babayigit, Ceren; Kurt, H.; Staliunas, Kestutis; Turduev, M. (2018-11-26)
      Article
      Open Access
      In this Letter, the design of a directional optical cloaking by a genetic algorithm is proposed and realized experimentally. A three-dimensional finite-difference time-domain method is combined with the genetic optimization ...

    • 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 ...
