Analysis of Photonic Crystal Tuned by Nematic Liquid Crystals

Abstract

Abstract-Modelling of left-handed metamaterial-based photonic nanostructures in functional optoelectronic devices have been studied in present paper. Two dimensional photonic crystal array on a narrow-band semiconductor base filled with a liquid crystal was analyzed. Photonic band structure and isofrequency contours of the nanostructures containing both inorganic and organic components were calculated for both TE and TM modes by using the plane wave expansion method. Silver telluride was used as a narrow-band semiconductor and E7 type as a liquid crystal. The photonic crystal structure that is designed as hexagonal rods shape in an air background is planned for the square lattice.
