Abstract
Optical deflectors have been used in a wide range of applications, from marking applications to optical links.Some of them are based on micro-electromechanical systems, now a growing
market. Another group of deflectors is founded on acousto-optic principle, in which there
is a change of a material's permittivity due to a mechanical wave. Other deviators are based on
an optical phased-array or rely on magneto-optic or electro-optic properties of some
materials. Usually, deviators without mechanics have a narrow angular range.
We present a new electro-optical deflector device based on electro-optical properties of
liquid crystal in which a graded-index is induced by the voltage applied in three electrodes. This
system permits to scan a wide angular range without mechanical elements.
First we will study the basics of the deflector; later on we will focus on the simulation of the
deviator and the properties of the device. Finally, we will show the experimental results through
the first deflector prototype.
