ABSTRACT:
An integrated optical modulator for modulating optical signals in dielectric wave guides with the modulator having a substrate with two wave guides on a surface thereof extending in parallel spaced relationship with each other and including three parallel extending electrodes arranged on the surface of the substrate to apply a voltage to the two wave guides characterized by the modulator including two additional short couplers in the form of short coupling wave guides with the short couplers being spaced from one another on the wave guides and extending at right angles thereto, the couplers being separated from the said two wave guides by a dielectric low loss film.
