Electro-optical Effect in a Coaxial Texture of Freely Suspended Ferroelectric Liquid Crystal Films

Abstract

Freely Suspended (FS) ferroelectric liquid crystal films have been fabricated successfully. Electro-optic measurements of FS films have been carried out. The optical response depends on the magnitude of the applied electricfield. The response to polarization reversal at intermediate field shows anomaly, in which piled 2π-walls are observed. The electro-optic response in the film has been analyzed on the basis of a switching model with a distribution function for the molecular orientation.
