The optical waveguide sections is disposed in the coupling element, the optical waveguide sections are disposed in at least two planes including a first plane and a second plane. The optical waveguide sections of different ones of the two planes are offset in relation to one another.

Abstract: To ensure laser safety, also in the case of a largest possible coupled optical power, during the direct optical coupling of a light-emitted component to an optical waveguide, an optical system includes coupling the light through a fiber end configured as a multimode step index optical waveguide having a numeric aperture larger than the half-width value of the angular distribution of the radiation emitted from the radiation source. To distribute the radiation fed into the actual optical waveguide over the largest possible angular range with regard to the luminous power, the coupling of the light beam into the fiber end is effected such that the coupled light beams are inclined in relation to the geometric axis of the optical core of the fiber end at a defined angle.

Abstract: A transmission device contains a plurality of laser transmitters that can be driven individually with a driving current and output optical signals and whose operating point is set via a respective bias current. Each bias current has an individual correction current impressed on it. The correction currents are dimensioned such that, for the same bias current, the laser transmitters have an identical or essentially more uniform average optical output power at the desired operating point.

Abstract: The optic coupling system links a fiber-optics waveguide with two optoelectronic components. The components are disposed on a substrate with an interposed beam-splitting layer. The light incidence or light emission surface of the first optoelectronic element is disposed perpendicular to the substrate. The coupling system is either a bi-directional transmitter and receiver module or a mono-directional transmitter or receiver module. To this end, the light incidence or light emersion surface of the second optoelectronic element is disposed in parallel to the substrate and the beam-splitting layer is disposed on a surface that is arranged above the second optoelectronic element at an angle of approximately 45° with respect to the substrate.

Abstract: The invention relates to an electro-optical module for transmitting and/or receiving optical signals on at least two optical data channels which are carried in an optical waveguide. The optical waveguide in the module forms at least two optical waveguide sections, with each section having at least one inclined end surface. The inclined end surfaces of the optical waveguide sections are positioned axially one behind the other. Light is injected into or light is output from the optical waveguide for a specific optical data channel by light for the optical data channel being passed to an inclined end surface, or emerging from it, at an angle to the optical axis of the optical waveguide.

Abstract: The module for optical signal transmission has a transmitting or receiving component mounted on a carrier. At least one optical waveguide, whose two ends represent an optical input and an optical output of the module, is associated with the transmitting or receiving component. A wavelength-selective element is arranged or formed in the optical waveguide and injects into the optical waveguide or outputs from it light, which is emitted from or received by the transmitting or receiving element, for a specific optical data channel. The light is injected into or output from the optical waveguide essentially at right angles to the optical axis of the optical waveguide.

Abstract: A coupling module contains a plurality of optical transmitters with an optically active zone in each case. Each transmitter is assigned an optical fiber end with a sloping end face that deflects radiation emitted by the transmitter.

Abstract: A coupling component includes a first substrate with a first alignment device and a plurality of optical waveguides located in one plane. The first substrate is a molded synthetic material body. The optical waveguides have coupling-side end surfaces causing a beam deflection onto optically active surfaces of a multichannel electrooptical converter. A second substrate has a second alignment device tuned or matched to the first alignment device of the first substrate. The converter is positioned on the second substrate independently of the optical waveguides and precisely with respect to the second alignment device. The alignment devices are formed by corresponding oblique surfaces on both substrates. The oblique surfaces in one dimension extend parallel to the longitudinal axes of the optical waveguides and are located in planes which intersect the plane of the optical waveguides.

Abstract: To produce a mechanically firm glued connection between two surface regions of surfaces to be connected, a method is provided which provides each of the surfaces with surface regions having a peak-to-valley thickness of less than 0.3 &mgr;m and the surface regions are brought together in such a way that an intermediate space, which is filled with the glue, is produced therebetween and the space has a small average thickness of less than 0.31 &mgr;m and extends over a surface area of at least 20×20 &mgr;m2. The glue is preferably brought into the intermediate space by capillary action and contacts of high quality can be achieved with this method.

The coupling gap is filled with a first light-permeable material. A second light-impermeable material protects an electrical circuit disposed in the immediate vicinity of the converter from outside light. The second material is equivalent in its basic chemical composition to the first material, but is modified in its optical properties for the sake of impermeability to light. At least one bonding wire serving to trigger the converter passes through the first and second materials.
