    • Coupled Plasmonic Cavities on Moire Surfaces 

      Balci, S.; Karabiyik, M.; Kocabas, A.; Kocabas, C.; Aydinli, A. (Springer New York LLC, 2010)
      Surface plasmon polariton (SPP) waveguides formed by coupled plasmonic cavities on metallic Moire surfaces have been investigated both experimentally and numerically. The Moire surface, fabricated by interference lithography, ...
    • Direct imaging of localized surface plasmon polaritons 

      Balci, S.; Karademir, E.; Kocabas, C.; Aydinli, A. (Optical Society of America, 2011)
      In this Letter, we report on dark field imaging of localized surface plasmon polaritons (SPPs) in plasmonic waveguiding bands formed by plasmonic coupled cavities. We image the light scattered from SPPs in the plasmonic ...
    • Observation of cavity structures in composite metamaterials 

      Caglayan, H.; Ozbay, E. (S P I E - International Society for Optical Engineering, 2010-07-29)
      We investigated the cavity structure by the deformation of a unit cell of a Composite Metamaterial (CMM) structure. We considered different cavity structures with different resonance frequencies and Q-factors. We observed ...
    • Slowing surface plasmon polaritons on plasmonic coupled cavities by tuning grating grooves 

      Balci, S.; Kocabas, A.; Kocabas, C.; Aydinli, A. (American Institute of Physics, 2010)
      We investigate slow surface plasmon polaritons (SPPs) in plasmonic waveguiding bands formed by coupled plasmonic cavities on Moiŕ surfaces. We demonstrate controlling the group velocity and dispersion of the SPPs by varying ...
    • Tight-binding mechanism in slow light regime 

      Akosman, A.E.; Mutlu, M.; Kurt H.; Ozbay, E. (2011)
      In this study, tight-binding formalism is applied to a photonic crystal coupled cavity structure in order to investigate the characteristics of ultra slow light modes. Eigen-mode splitting is observed and resulting group ...
