Abstract : In the patent, a traveling-wave electro-optical light modulator comprises an electro-optical crystal wafer with electrodes on the top and bottom surfaces and a high reflectivity coating covering the side surfaces except for two predetermined areas. A beam of light enters the crystal through one of these areas, is reflected a number of times between the two side surfaces, and leaves the crystal through the other area. The top electrode is in the form of a strip. The light beam passes under the strip once during each reflection. The strip lies on the crystal surface in such a manner that the travelingwave impressed on the electrodes is traveling in the same direction as the light beam when modulation occurs.
