The optical signals of the various wavelengths are combined or separated in a wavelength-selective manner. To combine or separate the individual wavelengths, only one wavelength-selective filter is used, and the optical signals are routed in such a way that they repeatedly strike the wavelength-selective filter at respectively different angles. The optical signals of only one specific wavelength are coupled in or out for each angle.

Abstract: A component contains a first array with a plurality of electro-optical converters for electro-optically converting a first light wavelength. Each of the electro-optical converters is optically coupled to a respective assigned wave guide. The aim of the invention is to increase the transmission capacity of such a component.

One of these additional electro-optical converters each is optically coupled to one of the plurality of wave guides.

Abstract: The optical transmission device comprises a transmitter which emits radiation vertically with respect to a covering surface. A reflection surface reflects a portion of the emitted radiation back onto an optically sensitive reception zone of a monitor receiver which is disposed on the same side as the transmitter. An intermediate body with a reflecting circumferential surface is disposed between the reflection surface and the reception zone. At least a portion of the reflected radiation passes from the circumferential surface to the reception zone, which significantly increases the yield of the reflected portion used for monitoring purposes.

Abstract: A method for producing of an electrooptical female connector element for an optical male connector of an electrooptical plug connector. In order to allow such a method to be carried out cost-effectively, a mounting module is used during the production of the female connector element. The mounting module is provided with alignment pins disposed on an end face, facing the male connector, in such a way that it corresponds to a configuration of alignment openings in the male connector. A component support having an electrooptical component with optical transducer elements is fitted on the end face of the mounting module, in a configuration corresponding to the optical conductor ends of the male connector. Once the male connector has been joined to the mounting module and the transducer elements have been actuated electrically, the component support is aligned to a position of maximum optical coupling.

The molded body has at least one functional surface, such as a lens or a stop face, serving the purpose of optical coupling.

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.
