Light Scattering of Short Helix Pitch Ferroelectric Liquid Crystal

Abstract

Two new light scattering modes have been discovered in short helix pitch (p 0 ffi 350 nm) ferroelectric liquid crystal (FLC). One of the modes arises because of a special kind of the FLC structure non-uniformity that originates inherently as a new phenomenon if the helix pitch is very small. Another mode relates to the helix twisting after the driving voltage switching off.
