One and two dimensional LiNbO3 photonic crystals
(IEEE, 2013)In this report, we present an investigation of the optical properties and band structure calculations for the photonic crystal structures (PCs) based on one-dimensional (1D) and two-dimensional (2D) ferroelectric LiNbO3 ... -
Spatial filters based on EBG structures with anisotropic-like dispersion
(IEEE, 2010)Bandpass and bandstop spatial filters based on the dielectric-rod EBG structures are proposed and validated for the frequency range from 18 to 25 GHz. The obtained experimental results are well consistent with the theoretical ... -
Wide-angle reflection-mode spatial filtering and splitting with photonic crystal gratings and single-layer rod gratings
(Optical Society of American (OSA), 2014)New diffractive optical elements offering a frequency tolerant, very efficient, high-pass and bandpass spatial filtering over a broad range of incidence angles are demonstrated by numerical simulations. The device operates ...
