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.

Abstract: 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 substrate sections symmetrically about an axis of symmetry.

Abstract: Formation of an optical modulator in an optical rib waveguide configuration in an epitaxial semiconductor layer is facilitated by using an electrode cladding (electrically conducting-optically transparent) layer for contacting the rib portion of the epitaxial layer. The electrode cladding layer is essentially a polycrystalline compound semiconductive material of suitably low refractive index and is advantageously characterized by a relatively high (0.4 to 1.0 volt or more) heterojunction potential barrier height at the epitaxial layer. The electrode cladding layer results in relatively low optical waveguide cladding loss as well as good electrode contact, thereby facilitating the application of a modulating electric field into the epitaxial rib waveguide during operation. The electrode cladding layer can also serve as a mask for controllably forming the rib portion with a predetermined rib height in the epitaxial layer.

Abstract translation: 通过使用用于接触外延层的肋部分的电极包层（导电光学透明）层，促进在外延半导体层中的光学肋波导配置中的光学调制器的形成。 电极包覆层基本上是适当低折射率的多晶化合物半导体材料，并且有利地在外延层处具有相对较高（0.4至1.0伏特或更高）异质结势垒势垒的特征。 电极包层导致相对低的光波导包层损耗以及良好的电极接触，从而有助于在操作期间将调制电场施加到外延肋波导中。 电极覆层也可以用作在外延层中以规定的肋高度可控地形成肋部的掩模。

Abstract: A waveguide-type optical circuit element which is equipped with a directional coupler that varies the intensity of light between two waveguides, and is used as a polarization-independent optical switch or a variable light- branching filter for optical fiber communication, etc. The length of the coupling portion of two waveguides (2) and (3) is, in the case of the TE mode, about three times as long as the complete coupling length of the TE mode. In the case of the TM mode, the length is nearly equal to the complete coupling length of the TM mode. Electrodes (4) and (5) each divided into three parts are inverted-Δβ electrodes in which the direction of the electric field is inverted alternately. Thus, the effect of confining the light in the waveguides is enhanced, and the driving voltage for optical switching is low. Optimum element characteristics are obtained according to the ratio of variations of the propagation constants of the TE and TM modes of the directional coupler fabricated.

Abstract: Ce coupleur comprend deux guides d'ondes G1, G2 recouverts d'électrodes. Selon l'invention, ces électrodes sont au nombre de 3 et leur chevauchement des guides alterne: dans la première section (S) les électrodes MB 1 et MB 2 recouvrent les guides G1 et G2 et la troisième électrode est très éloignée des deux autres; dans la deuxième section (S') les deuxième et première électrodes (MB' 2 , MB' 1 ) recouvrent les guides et la troisième est très éloignée des autres. Par ailleurs, les dimensions sont choisies pour que l'impédance de la ligne soit adaptée. Le coupleur est donc à la fois à déphasage alterné et à onde progressive.
Application en optique intégrée.
