A multilayer optical printed wiring board with a cube-core structure was developed for high-density optical interconnections. A fabricated multilayer optical printed wiring board with this cube-core structure has optical-coupling efficiency 2.7 dB higher than one without this structure. A fabricated optical interconnection model successfully demonstrated 10-Gbit/s/channel operation. These results show that the advantage of this cube-core structure is that it provides high optical-coupling efficiency in a high-density multilayer optical printed wiring board.
