    • 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 ...
    • Broadband quarter-wave plates at near-infrared using high-contrast gratings 

      Mutlu, M.; Akosman, A.E.; Kurt G.; Gokkavas, M.; Özbay, Ekmel (2013)
      In this paper, we report the theoretical and experimental possibility of achieving a quarter-wave plate regime by using high-contrast gratings, which are binary, vertical, periodic, near-wavelength, and two-dimensional ...
