Abstract
The radiation guide switching arrangement having at least one radiation guide switch is produced from a sandwich wafer. The sandwich wafer has a substrate, a covering layer and an electrically insulating intermediate layer. Each radiation guide switch has a moveable switching part ( ) as well as at least two radiation guide ends ( ), which come to rest in a plane and are arranged closely adjacent to one another such that radiation which emerges from one radiation guide end ( ) can be blocked on its optical path to another guide end ( ), or can be reflected into this other guide end, by means of the switching part ( ). The intermediate space ( ) which accommodates the switching part ( ) between the guide ends ( ) is filled with an index matching liquid ( ) which has a predetermined refractive index, and the radiation-carrying core ( ) of each radiation guide ( ) is designed to taper such that radiation collimation ( ) can be achieved by interaction with the refractive index of the index matching liquid ( ) and the free core profile ( ) in the space which is filled with liquid.
