• Waveguide asymmetric long-period grating couplers as refractive index sensors 

      Høvik, Jens; Yadav, Mukesh; Noh, Jong Wook; Aksnes, Astrid (Peer reviewed; Journal article, 2020)
      A highly sensitive integrated photonic transducer is designed by utilizing asymmetric long-period gratings on a silicon waveguide. These gratings are formed by periodic perturbation of the waveguide width, leading to ...
