ABSTRACT:
This e.g. Z-propagating, X-cut LiNbO.sub.3 :Ti splitter comprises an alternating delta beta directional coupler (39) able to introduce, in the absence of a voltage between its electrodes, a delta beta variation between its propagation constants, which is (a) independent of the polarization state of the guided lightwave and (b) such that the representative point of the coupler on its control diagram is the center of a segment parallel to the abscissa axis of the reference frame in which the diagram is plotted, and defined by two curves respectively corresponding to parallel states and crossed states of the coupler. Application to integrated optics.
