A light deflecting device including a flat, transparent light guide, and a transparent cover layer which is applied to the light guide at least partially in a flat manner. A microstructure for outcoupling light coupled into the light guide is formed between the light guide and the cover layer and the microstructure has a plurality of structural elements which are formed as substantially circular cylindrical elevations. A lighting device and the use of the light deflecting device or lighting device are also disclosed.

Light deflecting device, lighting device and use

The invention relates to the production of an electrooptical printed circuit board (EOLP) and to the use thereof. The optical layer in the printed circuit board is made of highly transparent and soldering bath-resistant polysiloxane wave guides. The polysiloxane wave guides are produced according to casting techniques, and the ends of the wave guides can comprise deviating mirrors which are integrated at 45&#xb0;. During the casting process of the printed circuit board, the substrate layers and the supersubstrate layers made of polysiloxane are brought into contact with printed circuit board materials having microstructured spacers which are used to define the thickness of the substrate layer and/or the thickness of the supersubstrate layer. Openings are located in the printed circuit board material above the deviating mirrors, such that vertical light decoupling and coupling can take place. The printed circuit board can be applied to rigid or flexible carrier materials as an optical link circuit, or can be used as an optical layer in a multilayer-board composite or as an integrated optical component.

Method for the production of electrooptical printed circuit boards comprising polysiloxane wave guides and use thereof

The invention relates to a method for linking two adjacent plastic work pieces (). The inventive method is characterized in that the intended contact zone (K) of at least one of the two work pieces () with which the latter adjoins to the other work piece () is at least partially subjected to a high-energy radiation to such an extent that the glass transition temperature is reduced in a marginal zone (R). The two work pieces () are brought in the desired position relative to each other. For establishing the connection of the two work pieces () at least the marginal zone (R) modified by the previous radiation process is heated at least in its surface area to a temperature that is higher than the glass transition temperature of the marginal zone (R) modified by the radiation process but lower than the glass transition temperature of the zones of the work pieces () that have not been modified. The invention also relates to an article () produced according to the inventive method that consists of two work pieces () that are linked without using foreign matte. The inventive article is characterized in that recesses (V), especially channel-shaped recesses, are introduced in at least one contact zone (K) of the two work pieces ().

Method for linking two plastic work pieces without using foreign matter

A method of manufacturing passive integrated optical devices from polymeric materials, the method comprising providing a step structure at each transition between a fiber alignment structure and the preform for the light waveguide structure, wherein both of these structures are produced simultaneously. Passive integrated optical devices having ridges or trenches with rectangular cross sections and manufactured to this method are also described.
