One and two dimensional LiNbO3 photonic crystals

Şimşek, Şevket; Mamedov, Amirullah M.; Özbay, Ekmel (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

Serebryannikov, A.E.; Cakmak, A.O.; Çolak, Evrim; Özbay, Ekmel (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

Serebryannikov, A. E.; Lalanne, P.; Petrov, A. Y.; Özbay, Ekmel (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 ...
