Analysis of Photonic Crystal Tuned by Nematic Liquid Crystals

Abstract

Modelling of left-handed metamaterial-basedphotonic nanostructures in functional optoelectronic devices havebeen studied in present paper. Two dimensional photonic crystalarray on a narrow-band semiconductor base filled with a liquidcrystal was analyzed. Photonic band structure and isofrequencycontours of the nanostructures containing both inorganic andorganic components were calculated for both TE and TM modesby using the plane wave expansion method. Silver telluride wasused as a narrow-band semiconductor and E7 type as a liquidcrystal. The photonic crystal structure that is designed ashexagonal rods shape in an air background is planned for thesquare lattice.
