Device for arranging light rays in a more compact dispositon

摘要

The device converts several light-beams (13) into a relatively compact arrangement of these light-beams, and includes several light-conducting layers (1) in which each layer has an injection end-face (11) for injecting the respective light beam into this layer (1). The tapping end-faces (12) and the light beams tapped from the tapping end-faces in a direction (Y) normal to a given plane ( (X,Y) ) are arranged over one another. The light-conducting layers comprise level, flat layers e.g. of SiO2 which are arranged parallel to the given plane ( (X,Y) ) and in a direction (Y) normal to this plane. In this direction, both the injection end-faces and the tapping end faces of the various layers are located over one another. A light-beam deflection device (17) is formed in each layer and deflects the injected light-beam carried in this layer to the tapping end-face such that the light-beams deflected from all the deflection devices (17) are incident one above the other on the tapping end-faces in the direction (Y) normal to the given plane ( (X,Y) ). The beams may be coupled to e.g. a multi- mode optical fibre.
