Abstract: The invention relates to a transmitter-receiver assembly by means of which light signals can be transformed into electric signals (receiver mode), or electric signals into light signals (transmitter mode). Said assembly comprises a component (10) comprising positioning configurations (16), an optical waveguide (17), a first mirror (14) and a second mirror (15), the two mirrors (14, 15) lying in prolongation of the optical waveguide (17), and the second mirror (15), as seen from the optical waveguide (17), lying behind the first mirror (14), as well as to a component (20) having adjustment configurations (23), an optical transmitter (29) and an optical receiver (25), the transmitter (29) and the receiver (25) being arranged next to one another.

Abstract: A circuit board (5) is described, consisting of at least two individual circuit board layers (10) made of plastics and produced by formation technique, which each have first and second functional sides and at least one microstructured positioning formation (16) on each of the first and second functional sides and at least one microstructured conductor trench (12) on one of the functional sides, the conductor trench (12) being provided with a metallization (18). This allows a low expenditure production of circuit boards having a high packing density.

Abstract: A substrate for an opto-electronic assembly comprises at least one receiving structure for an optical waveguide and at least one positioning structure for an opto-electronic component.

Abstract: An assembly unit comprises a printed circuit board (10) and an optical component (54, 56, 58), the printed circuit board (10) being provided with at least one electro-optical component (16), at least one conducting track (24) for the connection of the electro-optical component (16), as well as a three-dimensional, microstructured adjustment formation (12), the electro-optical component (16) being precisely arranged relative to the latter, and a three-dimensional positioning formation (52) being provided on the optical component (54, 56, 58) and cooperating with the adjustment formation (12) of the printed circuit board (10) in such a way that the optical component (54, 56 58) is precisely coupled with the electro-optical component (16) of the printed circuit board (10).

Abstract: Described is a polymer optical fiber including a section having a circular cross-section and a section having a non-circular cross-section. Also described are optical components containing such an optical fiber, as well as a method of fabricating such an optical fiber.

Abstract: To planarize an electroformed, magnetic metal sheet having micropatterns, the metal sheet is clamped on a magnet and is mechanically processed on the back side of the metal in such a way that it assumes a plane-parallel shape. Metal sheets can be used which are not stress-free and are obtained in a fast electroplating process. Multiple copying is possible.

Abstract: In a method for manufacturing an integrated, optical waveguide component having fiber couplings, a substrate component and a cover component are used, the cover component being obtained by forming a positive-negative replica of the substrate component. To separate the optical waveguide pattern region from the regions of the fiber couplings, grooves, as well as corresponding webs, are provided transversely to the fiber couplings. The method eliminates the need for carrying out the fiber adjustment and the waveguide formation in one process.
