    • Coupled plasmonic cavities on moire surfaces 

      Balcı, Sinan; Karabıyık, Mustafa; Kocabaş, Aşkın; Kocabaş, Coşkun; Aydınlı, Atilla (Springer, 2010-08)
      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 

      Balcı, Sinan; Karademir, Ertuğrul; Kocabaş, Coşkun; Aydınlı, Atilla (Optical Society of America, 2011-08)
      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 ...
    • Hybrid J-Aggregate–graphene phototransistor 

      Balcı, Osman; Uzlu, Burkay; Yakar, Ozan; Polat, Nahit; Ari, O.; Tunç, İlknur; Kocabaş, Coşkun; Balcı, Sinan (American Chemical Society, 2020)
      J-aggregates are fantastic self-assembled chromophores with a very narrow and extremely sharp absorbance band in the visible and near-infrared spectrum, and hence they have found many exciting applications in nonlinear ...
    • Localization of surface plasmon polaritons in hexagonal arrays of Moiré cavities 

      Balcı, Sinan; Kocabaş, Aşkın; Kocabaş, Coşkun; Aydınlı, Atilla (AIP Publishing, 2011-01)
      In view of the progress on the confinement of light, we report on the dispersion characteristics of surface plasmon polaritons (SPPs) on two-dimensional Moire surfaces in the visible part of the electromagnetic spectrum. ...
    • The mechanism of hydroquinone assisted photodegradation of PVC 

      Balcı, Sinan (Bilkent University, 2002)
      Pure poly(vinyl chloride) (PVC) degrades upon exposure of UV radiation (λ <300 nm) by the loss of HCl and formation of long conjugated structures known as polyenes. The mechanism of this process is fully understood and ...
    • Slowing surface plasmon polaritons on plasmonic coupled cavities by tuning grating grooves 

      Balcı, Sinan; Kocabaş, Aşkın; Kocabaş, Coşkun; Aydınlı, Atilla (American Institute of Physics, 2010-09)
      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 ...
