Electrooptic effect in a ferroelectric liquid crystal with a small helix pitch and a large spontaneous polarization
Beresnev L. A. , Blinov L. M., Dergachev D. I. , Kondrat'ev S. B.
The distinctive features of a newly detected electrooptic effect in a helicoidal ferroelectric liquid crystal are described. This effect involves an electric-field-induced change in the refractive-index anisotropy which is averaged over time and over the light-beam aperture.
