Abstract:
1. Device for transferring optical signals, comprising: at least one preferably planar optical conductor having a light-permeable section within at least a portion of a planar region of the conductor composed of a light-conducting core having at least two parallel interfaces extending along the planar region, wherein said interfaces are provided with coatings resulting in a reflection of light guided in the light-conducting core; at least one source for the emission of light through the light-permeable section; at least one receiver for receiving light through the light-permeable section; and at least one means for coupling said source or said receiver, respectively, to said optical conductor, wherein said means comprises optical coupling gratings for redirecting the light by diffraction, and said at least one of the optical gratings is embedded in said core.
