Ferroelectric Based Photonic Crystal Cavity by Liquid Crystal Infiltration
(Taylor & Francis, 2014)A novel type of two-dimensional photonic crystal is investigated for it optical properties as a core-shell-type ferroelectric nanorod infiltrated with nematic liquid crystals. Using the plane wave expansion method and ... -
Highly directional enhanced radiation from sources embedded inside three-dimensional photonic crystals
(Optical Society of America, 2005)We have experimentally studied emission of microwave radiation from a monopole source embedded in a three-dimensional photonic crystal. We have demonstrated enhancement of microwave radiation at the band edge and cavity ... -
Highly directive radiation from sources embedded inside photonic crystals
(American Institute of Physics, 2003)In this work, we have experimentally and theoretically studied the angular distribution of power emitted from a radiation source embedded inside a photonic crystal. Our results show that it is possible to obtain highly ... -
Localization of surface plasmon polaritons in hexagonal arrays of Moiré cavities
(AIP Publishing, 2011-01)In view of the progress on the confinement of light, we report on the dispersion characteristics of surface plasmon polaritons (SPPs) on two-dimensional Moire surfaces in the visible part of the electromagnetic spectrum. ... -
Quasimetallic silicon micromachined photonic crystals
(American Institute of Physics, 2001)We report on fabrication of a layer-by-layer photonic crystal using highly doped silicon wafers processed by semiconductor micromachining techniques. The crystals, built using (100) silicon wafers, resulted in an upper ... -
Solid-solution of Cd(formula)Zn(formula)S nanocrystals in the channels of mesostructured silica films
(Bilkent University, 2006)Mesostructured silica can be used as a reaction medium to produce solidsolution of Cd1-xZnxS nanocrystals as thin films. These films were synthesized from oligo(ethylene oxide) non-ionic surfactant (CH3(CH2)11(OCH2CH2)10OH, ...
