| Abstract(in English) | We predict for the first time that a continuous EO effect can exist in achiral Sm C LCs such that the director is made twisted by twice the molecular tilt on going from one substrate to the other. Unlike chiral Sm C* materials, this external twist is required for producing an induced cone in the Sm C phase so that the molecules rotate continuously along the cone surface formed by the requirement that the molecules are tilted with respect to the layer normal and pinned at the surfaces. As a consequence, a continuous optical modulation can be achieved by means of the dielectric anisotropy with no threshold. This EO effect is predicted in a twisted structure of achiral Sm C materials with either the positive and negative dielectric anisotropy. The basic principles of the optical modulation in such configuration are similar to those in a twist nematic LC geometry except for the existence of smectic layers and the intrinsic biaxiality |
