    • Compact wavelength de-multiplexer design using slow light regime of photonic crystal waveguides 

      Akosman, A.E.; Mutlu, M.; Kurt H.; Özbay, Ekmel (Optical Society of American (OSA), 2011)
      We demonstrate the operation of a compact wavelength demultiplexer using cascaded single-mode photonic crystal waveguides utilizing the slow light regime. By altering the dielectric filling factors of each waveguide segment, ...
    • Dual-frequency division de-multiplexer based on cascaded photonic crystal waveguides 

      Akosman, Ahmet E.; Mutlu, Mehmet; Kurt, H.; Özbay, Ekmel (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 ...
    • Enhanced electro-optic modulation of LiNbO3-based photonic crystal cavities with dual mode and polarization operation 

      Baǧcı, F.; Kurt G.; Akaoǧlu, B.; Özbay, Ekmel (TUBITAK, 2017)
      A high output transmission and high quality factor, compact LiNbO3 -based Fabry-Perot-type photonic crystal cavity is reported that can be used in electro-optical modulators at optical communication wavelengths. The ...
    • 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 ...
    • 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 ...
    • Tight-binding mechanism in slow light regime 

      Akosman, Ahmet Emin; Mutlu, Mehmet; Kurt, Hamza; Özbay, Ekmel (IEEE, 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 ...
