ABSTRACT:
The present invention relates to an optical device comprising an ionic conductor and a pair of electrodes, the ionic conductor being made of a material that is transparent to light and contains mobile ions and the electrodes being suitable for absorbing and desorbing the ions and being in ionic contact with the ionic conductor. The refractive index in at least a zone of the ionic conductor can be varied under the effect of the voltage applied between the electrodes. The electrodes contain an electrochemically active material selected from an active carbon, a conductive polymer, and an insertion material suitable for inserting ions in its structure.
