    • Asymmetric light propagation in chirped photonic crystal waveguides 

      Kurt H.; Yilmaz, D.; Akosman, A.E.; Özbay, Ekmel (Optical Society of American (OSA), 2012)
      We report numerical and experimental investigations of asymmetric light propagation in a newly designed photonic structure that is formed by creating a chirped photonic crystal (PC) waveguide. The use of a non-symmetric ...
    • In-chip microstructures and photonic devices fabricated by nonlinear laser lithography deep inside silicon 

      Tokel, O.; Turnalı, A.; Makey, G.; Elahi, P.; Çolakoǧlu, T.; Ergeçen E.; Yavuz, Ö.; Hübner R.; Borra, M. Z.; Pavlov, I.; Bek, A.; Turan, R.; Kesim, D. K.; Tozburun, S.; Ilday, S.; Ilday, F. Ö. (Nature Publishing Group, 2017)
      Silicon is an excellent material for microelectronics and integrated photonics 1-3, with untapped potential for mid-infrared optics 4 . Despite broad recognition of the importance of the third dimension 5,6, current ...
    • Multilayer graphene broadband terahertz modulators with flexible substrate 

      Kaya, E.; Kakenov, N.; Altan, H.; Kocabas, C.; Esenturk, O. (Springer New York LLC, 2018)
      Fabrication of terahertz modulators as simple devices with high modulation depth across a broad bandwidth is still very challenging. In this study, four different chemical vapor deposition grown multilayer graphene (MLG) ...
