Abstract : This patent discloses an electrooptical waveguide switching device comprising three sections of abutting crystalline substrates, the easy axis of each substrate being orthogonal to that of its neighbors. Each substrate is formed with a pair of waveguide sections which couple with those of the other sections, when the substrates are abutted, to form a pair of waveguide channels across the substrate sections. Sets of electrodes for directing horizontal and vertical electric fields through one waveguide channel are also formed on the substrates sections symmetrically about an axis of symmetry. (Author)
