    摘要： An improved optical isolator (6) for a semiconductor laser (2) for use in optical communication systems consists of a polarizer (4) and a birefringent medium (5). An electric field is applied to the birefringent medium (5) via electrodes (7) for varying the indices of refraction of the birefringent medium (5). By the variation of the indices of refraction, the optical isolator (6)can be adapted to different light wavelengths.

    摘要： An optical mode filter, that is, an optical component in which the basic mode can propagate undamped as much as possible but which in higher modes are strongly damped. The optical mode filter, is an integrated optical wave guide formed by, a higher-refracting or an absorbent material disposed near a flat wave guide core. Two buffer layers are located opposite the wave guide core, and one is formed with a thinned region to function as a filter for higher modes being transmitted through the wave guide core.

    摘要： An optical modulator having a slit arrangement and an associated zone exhibiting both an electrooptical effect and an intrinsic polarization direction, includes an electrode arrangement to which an information signal is applied during operation. The slit arrangement is a double slit arrangement while the electrode arrangement includes three electrodes between which the slits are disposed. At one slit, the electrical field of the signal is oriented in the same direction as the intrinsic polarization direction and, at the other slit, the electrical field of the signal is oriented in a direction opposite to the intrinsic polarization direction.

    摘要： A strain gauge comprised of a premagnetized ferromagnetic film wherein any change in length of the film can be measured by employing the properties of magnetostriction and magnetoresistance. The strain gauge is deposited on a substrate by thin-film techniques and has a very high sensitivity. Preferably, two electrically insulated strips parallel strips of amorphous metal film have (in the absence of strain) respective directions of magnetization aligned antiparallel to one another and are connected electrically at one end. Such an arrangement facilitates the reversion of the magnetization back to its easy direction when the stress causing the strain is removed.

    摘要： An optical component comprising an optical waveguide and adjacent to it at least one grating array adapted to reflect stray light away from said optical waveguide. The use of a grating array with a plurality of structures like polygons or stripes gives the possibility to define a multiple of reflection directions. This is obtained by using polygons layed out in different orientations up to a random one or a Bragg grating preferably defined with a non-uniform period (chirped). Such grating arrays are usually structured within the same layer as the optical waveguide core layer.

    摘要： It is an object of the invention to provide a network topology for OCDM signals. Coding splitters combining both coding and splitting functions are provided. The coding splitters themselves can be made from cascaded Mach Zehnder filters which are located somewhere in the network and which can be integrated using planar waveguide technologies. Each OCDM transceiver as well as the network is connected to the splitter via a pair of fibers for the two transmission directions. This set-up has the advantage that the same splitter can be used for both directions to and from the transceivers on one side and to and from the network on the other side.

    摘要： Methods for the production of printed circuit boards (1) with at least one electrically conductive through-plating which runs in a hole (5) in an insulating base material (2) from a first to a second surface include the following steps. The base material is pressed on its surfaces with two-layered foils (3, 4) consisting of a Cu foil (31, 32) covered with a Cu layer (32′, 42′), an acrylonitrile-butadiene-styrene-copolymer film (32″, 42″) or a self-adhesive plastic film (32*, 42*) in such a way that the Cu foils adhere well to the base material. The holes are produced and they as well as the exposed surfaces of the layers (32′, 42′; 32″, 42″; 32*, 42*) are provided with a further Cu layer (6, 6′). The metallized holes are completely filled with an insulating material (7) or with a conductive material (7′; 8) by spreading on with a squeegee or by rolling on to the exposed surface of the Cu layer (6, 6′). The layers (32′, 42′; 32″, 42″; 32*, 42*) are removed together with the Cu layer (6, 6′). Stubs (71, 72; 81, 82) which project beyond the remaining Cu foils (31, 41) are removed after the curing of the material (7, 7′; 8) thereby planarizing the Cu foils (31, 41) being now ready for structuring to produce a conductive pattern.
