ABSTRACT:
An electro-optical switch for switching optical radiation between two wave guides having a coupling zone with two pairs of electrodes (E.sub.11, E.sub.12, E.sub.21, E.sub.22) respectively associated with two guides (1, 2) and positioned so as to cover a variable fraction of the width of the guides. As a result, the electro-optical effects produced and, therefore, the propagation velocities in the two guides are made variable as a function of the electrical connection mode of the electrodes. Two switching states are obtained with a considerable tolerance for the length of the guides (2L) and the control voltage.
