    • Absorption enhancement of molecules in the weak plasmon-exciton coupling regime 

      Balci, S.; Karademir, E.; Kocabas, C.; Aydınlı, Atilla (Optical Society of American (OSA), 2014)
      We report on the experimental and theoretical investigations of enhancing the optical absorption of organic molecules in the weak plasmon-exciton coupling regime. A metal-organic hybrid structure consisting of dye molecules ...

    • Electrically switchable metadevices via graphene 

      Balcı, Osman; Kakenov, Nurbek; Karademir, E.; Balcı, S.; Çakmakyapan, S.; Polat, E. O.; Cağlayan, H.; Özbay, Ekmel; Kocabaş, Coşkun (American Association for the Advancement of Science, 2018)
      Metamaterials bring subwavelength resonating structures together to overcome the limitations of conventional materials. The realization of active metadevices has been an outstanding challenge that requires electrically ...

    • Lasing in a Slow Plasmon Moiré Cavity 

      Karademir, E.; Balci, S.; Kocabas, C.; Aydınlı, Atilla (American Chemical Society, 2015)
      We report on lasing from dye-based excitons coupled to slow plasmon states inside metallic Moiré cavities. Surface plasmon polaritons (SPPs) inside the cavity were slowed down to a maximum group velocity of 0.3c. Varying ...

    • Plasmonic band gap engineering of plasmon-exciton coupling 

      Karademir, E.; Balci, S.; Kocabas, C.; Aydınlı, Atilla (Optical Society of American (OSA), 2014)
      Controlling plasmon-exciton coupling through band gap engineering of plasmonic crystals is demonstrated in the Kretschmann configuration. When the flat metal surface is textured with a sinusoidal grating only in one ...

    • Plexcitonic crystals: A tunable platform for light-matter interactions 

      Karademir, E.; Balci, S.; Kocabas, C.; Aydınlı, Atilla (Optical Society of American (OSA), 2014)
      Coupled states of surface plasmon polaritons (SPPs) and excitons are collectively called plexcitons [Nano Lett. 8, 3481 (2008)]. Plexcitonics is an emerging field of research aiming to control light-matter interaction at ...

    • Slow plasmons in grating cavities 

      Aydınlı, Atilla; Karademir, E.; Balcı, S.; Kocabaş, Coşkun (SPIE, 2016)
      Recent research on surface plasmon polaritons and their applications have brought forward a wealth of information and continues to be of interest to many. In this report, we concentrate on propagating surface plasmon ...

    • Strong coupling between localized and propagating plasmon polaritons 

      Balci, S.; Karademir, E.; Kocabas, C. (OSA - The Optical Society, 2015)
      We investigate plasmon-plasmon (PP) coupling in the strongly interacting regimes by using a tunable plasmonic platform consisting of triangular Ag nanoprisms placed nanometers away from Ag thin films. The nanoprisms are ...

    • Tuning surface plasmon-exciton coupling via thickness dependent plasmon damping 

      Balci, S.; Kocabas, C.; Ates, S.; Karademir, E.; Salihoglu, O.; Aydınlı, Atilla (American Physical Society, 2012)
      In this paper, we report experimental and theoretical investigations on tuning of the surface plasmon-exciton coupling by controlling the plasmonic mode damping, which is defined by the plasmonic layer thickness. The results ...
