    • All-fiber Yb-doped laser mode-locked by nanotubes 

      Zhang, Zewang; Popa, D.; Sun, Z.; Hasan, T.; Ferrari, A.C.; İlday, F. Ömer (IEEE, 2013)
      Single-wall carbon nanotubes (SWNTs) and graphene have emerged as promising saturable absorbers (SAs), due to their broad operation bandwidth and fast recovery times [1-3]. However, Yb-doped fiber lasers mode-locked using ...
    • Broadband circular polarizer based on high-contrast gratings 

      Mutlu, M.; Akosman, A. E.; Özbay, Ekmel (Optical Society of America, 2012-05-30)
      A circular polarizer, which is composed of periodic and two-dimensional dielectric high-contrast gratings, is designed theoretically such that a unity conversion efficiency is achieved at λ0 = 1.55 μm. The operation is ...
