Device for transmission of optical signals by planar light conductors, has coupling arrangement containing grids for deflecting light by diffraction

摘要

The device has at least one preferably planar light conductor with a light conducting core with at least two reflectively coated parallel boundary surfaces in light guide regions, at least one light source and receiver and at least one arrangement for coupling the source and receiver to the light conductor. The coupling arrangement contains grids for deflecting the light by diffraction. INDEPENDENT CLAIM is included for a method of coupling at least one light source and at least one receiver to at least one preferably planar light conductor.
