Ferroelectric liquid crystals
2014 A general symmetry argument is presented, and experiments on newly synthesized p-decyloxybenzylidene p’-amino 2-methyl butyl cinnamate are described, demonstrating that chiral smectic C and H liquid crystals are ferroelectric. Some of the properties of this new class of ferroelectrics are discussed. In spite of speculation on the possibility of ferroelectric liquid crystalline phases [1], ...
متن کاملLinear electroclinic coupling in ferroelectric liquid crystals
We report a study of the electrodmic coupling (soft mode), close to the smectic A to smectic C* phase transition in several chiral compounds The main charactenstic of the technique used is to measure both optical and dielectric quantities on a single sample This
متن کاملFork gratings based on ferroelectric liquid crystals.
In this article, we disclose a fork grating (FG) based on the photo-aligned ferroelectric liquid crystal (FLC). The Digital Micro-mirror Device based system is used as a dynamic photomask to generated different holograms. Because of controlled anchoring energy, the photo alignment process offers optimal conditions for the multi-domain FLC alignment. Two different electro-optical modes namely DI...
متن کاملProperties and Applications of Ferroelectric Liquid Crystals
The ferroelectric modes of liquid crystals which allow for easy reorientation of the direction of polarization make liquid crystals an attractive element to use for applications such as optical storage, and optical switching. Three schemes for achieving ferroelectricity are discussed: chiral smectic alignment, achiral “banana-shaped” smectic alignment, and the nematic phase that comes from stro...
متن کاملPhotorefractive effect of ferroelectric liquid crystals.
This paper reviews our recent work on the photorefractive effect of ferroelectric liquid crystals (FLCs). The photorefractive effect is defined as the optical modulation of the refractive index of a medium as a result of a variety of processes. The interference of two laser beams in a photorefractive material establishes a refractive index grating. This phenomenon enables the creation of differ...
