    • Dual-frequency division de-multiplexer based on cascaded photonic crystal waveguides 

      Akosman, A. E.; Mutlu, M.; Kurt, H.; Ozbay, E. (Elsevier, 2012-02-28)
      A dual-frequency division de-multiplexing mechanism is demonstrated using cascaded photonic crystal waveguides with unequal waveguide widths. The de-multiplexing mechanism is based on the frequency shift of the waveguide ...
    • Lasing in a Slow Plasmon Moiré Cavity 

      Karademir, E.; Balci, S.; Kocabas, C.; Aydinli, A. (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 ...
    • Slowing down surface plasmons on a Moiré surface 

      Kocabas, A.; Senlik, S. S.; Aydinli, A. (The American Physical Society, 2009)
      We have demonstrated slow propagation of surface plasmons on metallic Moiré surfaces. The phase shift at the node of the Moiré surface localizes the propagating surface plasmons and adjacent nodes form weakly coupled ...
    • 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 ...
