Abstract

An electro-optical light deflector utilizing layers of a non-linear electro-optically (NLO) responsive polymer for directing an exiting light beam in a given direction. Sandwiched between each NLO layer of a multi-layer array is a thin film electrically conductive layer that is connected to a voltage source. By applying an electric field across an NLO layer, a change in refractive index is induced and the phase of that portion of the optical beam passing through it is either retarded or advanced. Each layer in the NLO array sees a slightly different electric field and therefore produces a slightly different phase change in the portion of the propogating optical beam. This results in directing the reconstructed beam in a different direction. By applying different voltages to the electrodes, both beam shaping and changing beam direction are possible.
