ABSTRACT:
An electro-optical modulator comprises a block of electro-optical material, a pattern of interdigitated electrodes on one face of the material, a source of light adapted to provide a non-convergent beam of light and arranged to apply said beam directly to the block of material so as to suffer a single internal reflection from said one face and to travel in the general direction of the length of the electrodes, and means for applying a modulating voltage to the electrodes.
