OPTICAL INTERCONNECTION SYSTEM USING OPTICAL WAVEGUIDE-INTEGRATED OPTICAL PRINTED CIRCUIT BOARD

摘要

An optical interconnection system is provided. The optical interconnection system includes an optical printed circuit board (PCB) that includes transmitter-unit and receiver-unit optical interconnection blocks for bending an optical path by a predetermined angle, an one-unit optical waveguide including an optical waveguide which is inserted into each of the optical interconnection blocks so as to connect optical paths of the transmitter-unit and receiver-unit optical interconnection blocks, and a PCB having the one-unit optical waveguide integrated therein; a light emitting element that is formed in-line with the optical waveguide on a top-surface of the transmitter-unit optical interconnection block exposed to a top-surface of the optical PCB; a driver integrated circuit that is formed on the top-surface of the optical PCB and electrically connected to the light emitting element and the optical PCB; a light receiving element that is formed in-line with the optical waveguide on a top-surface of the receiver-unit optical interconnection block exposed to the top-surface of the optical PCB; and a receiver integrated circuit that is formed on the top-surface of the optical PCB and electrically connected to the light receiving element and the optical PCB. The top-surfaces of the respective optical interconnection blocks are substantially aligned with the top-surface of the PCB.
