Abstract
An optical interconnection system is provided and 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, a 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 an upper surface of the transmitter-unit optical interconnection block exposed to an upper surface of the optical PCB; a driver integrated circuit that is formed on the upper 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 an upper surface of the receiver-unit optical interconnection block exposed to the upper surface of the optical PCB; and a receiver integrated circuit that is formed on the upper surface of the optical PCB and electrically connected…
