Item Open Access Chiral Structures: Manipulation of Asymmetric Transmission in Planar Chiral Nanostructures by Anisotropic Loss (Advanced Optical Materials 7/2013)(2013) Li, Z.; Gokkavas, M.; Özbay, EkmelAsymmetric transmissions of circularly polarized optical waves can be achieved when the waves are incident normal to planar chiral structures, provided that the structures are anisotropic and lossy. In order to clarify how the factor of loss affects the asymmetric transmission, Z. Li, M. Gokkavas, and E. Ozbay studied a typical planar chiral structure by using an optical lumped element model. On page 482, they found that the anisotropy of loss, instead of the whole loss, plays a crucial role for achieving asymmetric transmission. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.Item Open Access Iterative size reduction technique for optical nanostructures(Optical Society of America, 2012) Khudiyev, Tural; Bayındır, MehmetOne-dimensional optical nanostructures are mass produced from a macroscopic semiconductor rod by using a new top-to-bottom fabrication approach. These nanostructures, which can be easily scaled up to 2D and 3D, exhibit sizedependent double coloration mechanisms. © OSA 2012.Item Open Access Manipulation of Asymmetric Transmission in Planar Chiral Nanostructures by Anisotropic Loss(Wiley, 2013) Li, Z.; Gokkavas, M.; Özbay, EkmelPlanar chiral structures may provide asymmetric transmission for circularly polarized optical waves at normal incidence if the structures are anisotropic and lossy, but the role of loss has not yet been clarified. Here, a typical planar chiral structure is studied, and the mechanism of asymmetric transmission is analyzed. It is demonstrated for the first time that asymmetric transmission can be manipulated by changing the anisotropy of loss.
