Abstract:This paper reviews recent research performed at the liquid crystals laboratory of the A. V. Shubnikov Institute of Crystallography, Russian Academy of Sciences, focusing on photonic liquid crystalline structures induced by electric fields. Due to field-induced spatial modulation of the refractive index, such structures exhibit optical properties characteristic of photonic crystals. Two types of structures are discussed. The first type is induced in cholesteric liquid crystals with spontaneous formation of a he… Show more
