    • Enhanced tunability of V-shaped plasmonic structures using ionic liquid gating and graphene 

      Ozdemir, O.; Aygar, A. M.; Balci, O.; Kocabas, C.; Caglayan, H.; Ozbay, E. (Elsevier Ltd, 2016)
      Graphene is a strong candidate for active optoelectronic devices because of its electrostatically tunable optical response. Current substrate back-gating methods are unable to sustain high fields through graphene unless a ...
    • Observation of defect formation in metamaterials 

      Caglayan H.; Bulu I.; Loncar, M.; Ozbay, E. (Optical Society of America, 2008)
      We report subwavelength localization of electromagnetic fields within cavities based on metamaterials. Cavity resonances are observed in the transmission spectrum of a split ring resonator and composite metamaterials cavity ...
