Board-to-board optical interconnection between optical waveguide channels is suitable for high-speed optoelectronic printed wiring boards (OE-PWBs). Here, we propose a novel optical interconnection method based on plug-in alignment between an optical waveguide plug (OWP) and a micro hole array (MHA). The OWP and MHA are prepared from UV-curable resin and fabricated by the mask transfer method. As they are well-aligned on the optical waveguide channels of the OE-PWBs, both optical circuits of the OE-PWBs can be interconnected easily. From experimental results, we found that the plug-in alignment technique is promising for board-to-board optical interconnection.
