2D anisotropic photonic crystals of hollow semiconductor nanorod with liquid crystals
(2013)Photonic crystals (PCs) have many applications in order to control light-wave propagation. A novel type of two-dimensional anisotropic PC is investigated band gap and optical properties as a hollow semiconductor nanorod ... -
Broadband circular polarizer based on high-contrast gratings
(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 ...
