Ferroelectric liquid crystal tunable filters

Annual Meeting Optical Society of America, 1989
Rapidly tunable optical filters have applications in remote sensing, signal processing, colorimetry, color displays, and communications. In this paper we present simulation and experimental results of electronically tunable filter structures employing smectic A* electroclinic and smectic C * liquid crystals.

Ferroelectricity in Liquid Crystals

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 1999
Abstract After summarizing ferroelectric and antiferroelectric liquid crystals (LCs) in liquid crystals so far discovered, two materials exhibiting a proper ferroelectricity are reported; (1) polar order in nematic LC of aromatic polyesters and (2) ferroelectric switching in a lyotropic liquid crystal of polypeptide.

Ferroelectric Liquid Crystals

Molecular Crystals and Liquid Crystals Incorporating Nonlinear Optics, 1988
Abstract The idea either to reveal or to construct a liquid ferroelectric was never abandoned by researchers since the discovery of ferroelectricity in solid crystals at the beginning of this century. In principle, nature does not forbid the existence of ferroelectric liquids.

Ferroelectric Liquid Crystals

Molecular Crystals and Liquid Crystals Incorporating Nonlinear Optics, 1987
Abstract The main advances in the field of bulk ferroelectric liquid crystals since 1984 are reviewed. Recent experiments have shown that the molecular tilt and the in-plane spontaneous polarization are not strictly proportional to each other as assumed before.

Solitary Waves in Ferroelectric Liquid Crystals

Physical Review A, 1986
Since their discovery by Meyer et al. in 1975,1 ferroelectric liquid crystals (FLCs) in the smectic C phase have been the focus of a considerable research effort. It is now well established thay any tilted smectic liquid crystalline phase composed of chiral molecules should possess a permanent electric polarization P which is oriented perpendicular to ...

Stroboscopic microscopy of ferroelectric liquid crystals

Physical Review E, 1993
We have studied the switching of surface-stabilized ferroelectric-liquid-crystal (SSFLC) cells using stroboscopic microscopy. We find that the switching process in the chevron-layer-shaped SSFLC's is mediated by domains that occur at the chevron interface and that are nucleated both heterogeneously and homogeneously; that some features of the growth of

Ferroelectric liquid-crystal digital scanner

Optics Letters, 1990
The design and performance of a digital scanner based on ferroelectric liquid-crystal switchable wave plates and passive nematic liquid-crystal prisms are reported. The liquid-crystal prisms function as low-cost, integrable, lowangle birefringent prisms. A 1 x 64 scanner was built with -5.3 dB of average loss.

Ferroelectric liquid crystals versus dyed ferroelectric liquid crystals in SmC∗ phase

Physics Letters A, 2007
In order to study the effect of mixing dye in FLC materials the dielectric and electro-optical properties of pure and Anthraquinone dye doped FLC samples have been investigated. All the properties have been found to be strongly dependent on dye concentration in pure FLC.
