Abstract: A test apparatus for electro-optical printed circuit boards having optical waveguides comprises a control device, a beamer and a camera, which can be positioned in such a way that light emitted by the beamer can be coupled by means of a first deflecting element to optical waveguides of the circuit board and can be coupled out by means of a second deflecting element into the field of vision of the camera. The beamer is used in a first phase to determine the position for each deflecting mirror of the first deflecting element which a light spot needs to assume in the image projected by the beamer so that the light spot illuminates the deflecting mirror. The beamer is used in a second phase to illuminate at least one deflecting mirror and to carry out the testing of the optical waveguide associated with the at least one deflecting mirror.

Abstract: An electro-optical printed circuit board contains electrical conductor tracks on the one hand and optical waveguide structures on the other hand. The optical waveguide structures comprise a bottom layer, a core layer and a cladding layer. Visible areas are applied to the printed circuit board, and the core layer is applied later both to the bottom layer as well as the visible areas and structured both on the bottom layer as well as the visible areas. This structure is then transferred to the visible areas, e.g. by etching. Reference marks are thus produced which contain the information on the actual position of the optical waveguide structures.

Abstract: A coupling element (3) and a waveguide structure (4) are deposited on a common substrate (2) of an optical component (1). The coupling element (3) serves for the optical coupling of the waveguide structures (4) to a further optical component. The coupling element (3) contains a reflecting, curved surface (31.1-31.8) for deflecting and for collimation of light which propagates between the waveguide structure 4 and the further optical component. The coupling element (3) creates a standard for interfaces between the optical component (1) and a further optical component. The manufacture of the coupling element (3) is simple and inexpensive, may be standardized and directed to large batch numbers.
