    • Flat Optics for Compact Augmented Reality Systems: Diffractive Optical Elements and Metasurfaces 

      Pedersen, Ole Bjørn Eithun (Master thesis, 2021)
      I denne masteroppgaven presenterer vi fire forskjellige flat-optikk (flat optics) implementeringer av to klassiske arkitekturer for utvidet virkelighet (AR): stråledeler-arkitekturen og friform-arkitekturen. Tradisjonelt ...

    • Fluorophore Coupling to Internal Modes of Bragg Gratings 

      Badugu, Ramachandram; Mao, Jieying; Zhang, Douguo; Descrovi, Emiliano; Lakowicz, Joseph R. (Journal article, 2020)
      Multilayer structures with two dielectrics having different optical constants and no structural features in the x–y plane can display photonic band gaps (PBGs) and are called one-dimensional photonic crystals (1DPCs). If ...

    • Polarization-driven reversible actuation in a photo-responsive polymer composite 

      Urban, David; Marcucci, Niccolò; Wölfle, Christoph Hubertus; Torgersen, Jan; Hjelme, Dag Roar; Descrovi, Emiliano (Peer reviewed; Journal article, 2023)
      Light-responsive polymers and especially amorphous azopolymers with intrinsic anisotropic and polarization-dependent deformation photo-response hold great promises for remotely controlled, tunable devices. However, dynamic ...

    • Tunable photo-responsive elastic metamaterials 

      Descrovi, Emiliano (Peer reviewed; Journal article, 2020)
      The metamaterial paradigm has allowed an unprecedented space-time control of various physical fields, including elastic and acoustic waves. Despite the wide variety of metamaterial configurations proposed so far, most of ...

    • Tunable topological edge modes in Su-Schrieffer-Heeger arrays 

      Chaplain, G.J.; Gliozzi, A.S.; Davies, B.; Urban, David; Descrovi, Emiliano; Bosia, F.; Craster, R.V. (Peer reviewed; Journal article, 2023)
      A potential weakness of topological waveguides is that they act on a fixed narrow band of frequencies. However, by 3D printing samples from a photo-responsive polymer, we can obtain a device whose operating frequency can ...
