    • 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 ...

    • 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 ...

    • Nanostructured multilayer coatings for spatial filtering 

      Grineviciute, Lina; Babayigit, Ceren; Gailevicius, Darius; Peckus, Martynas; Turduev, Mirbek; Tolenis, Tomas; Vengris, Mikas; Kurt, Hamza; Staliunas, Kestutis (2021-03-16)
      Article
      Open Access
      Spatial filtering is an important mechanism to improve the spatial quality of laser beams. Typically, a confocal arrangement of lenses with a diaphragm in the focal plane is used for intracavity spatial filtering. Such ...

    • Numerical and experimental demonstration of a wavelength demultiplexer design by point-defect cavity coupled to a tapered photonic crystal waveguide 

      Hayran, Zeki; Turduev, Mirbek; Botey Cumella, Muriel; Herrero Simon, Ramon; Staliunas, Kestutis; Kurt, Hamza (2016-01-01)
      Article
      Open Access
      We propose and experimentally demonstrate a demultiplexer with point-defect resonators and a reflection feedback mechanism in a photonic crystal waveguide (PCW). A tapered PCW has been chosen as the necessary reflector, ...

    • Tunable wavelength-demultiplexer by tapered photonic crystal waveguide 

      Hayran, Zeki; Turduev, Mirbek; Botey Cumella, Muriel; Herrero Simon, Ramon; Staliunas, Kestutis; Kurt, H. (Institute of Electrical and Electronics Engineers (IEEE), 2015)
      Conference report
      Open Access
      We numerically investigate the design of a wavelength de-multiplexer based on a tapered photonic crystal waveguide. The tapered waveguide is generated by reducing the width of the channel which, in turn, provides a gradual ...
