Date Aug. 27, 1987.A device for providing information transferring communication between circuits (11), for instance, IC circuits on a substrate (10) by using coherent radiation. The substrate is formed from a material that is transparent to the radiation. The edge sides of the substrate not actively used for transfer of information are coated by a radiation absorbing or reflection preventing material. The circuits are placed in exactly defined positions (12), with at least portions thereof inside the substrate. These portions of the circuits are provided with input and output elements respectively (17, 16) which respond to the radiation, and which input and output elements are, by virtue of the positioning of the circuits, arranged for communication by direct linear propagation of the radiation through the substrate material without reflection at surfaces of the substrate.
