Abstract: A security element has at least two luminescent substances, in which the security element has a first and a second luminescent substance which have a substantially identical, joint emission band. The first or the second luminescent substance, or both luminescent substances, have at least one excitation band that leads to an emission at the joint emission band only in the case of the first or the second luminescent substance.

Abstract: The invention relates to a method and a sensor for checking a value document which is moved relative to the sensor. The sensor is arranged to detect the luminescence of the value document in two different spectral regions at the same location of detection simultaneously. The two temporal intensity patterns of the first and second luminescences detected in different spectral regions are evaluated relative to each other. This eliminates the motion effects which distort the two intensity patterns in the same or at least very similar manner.

Abstract: 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.

Abstract: 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.

Abstract: 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′).

Abstract: The invention relates to a self-centering arrangement of microstructured elements, particularly of microoptical components on a substrate serving as carrier. To provide microoptical components with projections that fit into corresponding recesses is known in the art. The invention provides a way to improve the mutual alignment of components (K1, K2) in that a deformation occurs when projections (Z1, Z2) are inserted into the recesses (A). This deformation may concern the projections or the recesses themselves or a molding material introduced between the projections and the recesses. The deformation improves the self-centering properties; in addition, manufacturing tolerances are more easily compensated. If the element cannot be provided with a suitable projection, an intermediate carrier is used, which is, for example, a plastic element produced by a LIGA process.

Abstract: 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.

Abstract: An optical hybrid switch is indicated, which guides a voltage-controlled light flux supplied by an incoming passive optical waveguide (1), to at least one of two outgoing passive optical waveguides (1, 1a). The hybrid switch according to the invention preferably uses a NLO-polymer as the electro-optically active elements. The increased attenuation linked to the use of NLO-polymer is kept low by extending the incoming optical waveguide (1) without interruption as one of the outgoing optical waveguides. To steer the light flux to the other outgoing optical waveguide (1a), the light is coupled out from an electro-optically active waveguide structure (5) by an adjustable coupler (6), and coupled to the other outgoing passive waveguide (1a) through another fixed adjustment coupler (8).
