Tunable Filters from Lyotropic Liquid Crystals
نویسندگان
چکیده
The external field influence on the birefringence of the liquid crystalline layer is expressed by using the Cauchy dispersion equation. The basically theoretical elements of the polarization interferential filters of Lyot Ohmann and Wood type, achieved in a multilayer geometry, are given in this paper. The expressions corresponding to the transmitted maxima and to the spectral bandwidths of the transmitted bands are established here.

متن کاملNanofabrication of highly ordered, tunable metallic mesostructures via quasi-hard-templating of lyotropic liquid crystals
The synthesis of metal frameworks perforated with nanotunnels is a challenge because metals have high surface energies that favor low surface area structures; traditional liquid-crystal templating techniques cannot achieve the synthetic control required. We report a synthetic strategy to fabricate metal nanomaterials with highly ordered, tunable mesostructures in confined systems based on a new...
متن کاملAlignment of high-aspect ratio colloidal gold nanoplatelets in nematic liquid crystals
We study elasticity-mediated alignment of anisotropic gold colloids in liquid crystals. Colloidal gold particles of controlled shapes (spheres, rods, and polygonal platelets) and sizes are prepared using well-established biosynthesis techniques with varying solvent conditions. When introduced into liquid crystalline structured solvents, these gold particles impose tangential or vertical surface...
متن کاملLyotropic Ferronematic Liquid Crystals Based on New Ni, Cu and Zn Ionic Magnetic Fluids
The properties of lyotropic ferronematic liquid crystals based on new Ni, Cu and Zn ionic magnetic uids are discussed. The eÆciency of these new ferro uids in the lyotropic nematic liquid crystal doping is veri ed and compared with the conventional surfacted ferro uid lyotropic doping. It was observed that the structural characteristics of the lyotropics and ferro uids determine the good format...
متن کاملLiquid crystal parameter analysis for tunable photonic bandgap fiber devices.
We investigate the tunability of splay-aligned liquid crystals for the use in solid core photonic crystal fibers. Finite element simulations are used to obtain the alignment of the liquid crystals subject to an external electric field. By means of the liquid crystal director field the optical permittivity is calculated and used in finite element mode simulations. The suitability of liquid cryst...
