Liquid-crystalline phases combine anisotropic properties and mobility
(1,2). This combination gives rise to a set of optical and electro-opt
ical switching processes which can be exploited in appropriate devices
for the purpose of modulating the intensity, polarization or directio
n of the light, for information storage or the manufacturing of hologr
aphic optical elements (3). The basic process involved is a modificati
on of the refractive index n and its anisotropy.
