Fusion of Fiber-Optic and PCB Technologies for In-board Optical Interconnection

To implement an optically-data-linked computer system, we proposed a chip-to-chip optical interconnection platforms based on fiber-embedded printed-circuit boards (PCBs) and fiber-optic components for assembly. The 90deg deflection of light between the optical PCB and transceiver modules were achieved using 90deg-bent fiber blocks. The connection blocks and optical transceiver modules were passively assembled in/on the optical PCB, employing the guide pins/hole of the conventional ferrules. An optical link of 7 Gb/s/ch signals with a low optical loss of -5.3 dB have been demonstrated from the assembled platform.
