Smectic nanostructures with typical size less than the visible light wavelength: physics and electro-optics

Evgeny Pavlovich Pozhidaev, Vadim Evgenievich Molkin, Vladimir Grigorievich Chigrinov


Very short helix pitch (p0~150-200nm) ferroelectric liquid crystals (FLCs) have been developed. Electro-optical cells based on these mixtures are free from selective reflection and diffraction in the visible spectral range and therefore exhibit very perfect operation in deformed helix ferroelectric (DHF) mode. Two main electro-optical modes of DHF cells with sub-wavelength helix pitch are under consideration
