Description
特許文献1(特許2546688号)によると、光導波路基板の表面部分に帯状の光導波路が設けられ、光導波路の両末端部の基板側には表面側に開口した凹部が形成され、光導波路の両端面に対向する基板側は、光導波路の光軸に45度傾斜した斜め上向きの反射壁を構成している。したがって、光導波路基板に対して垂直に入射した光は、一方の45度傾斜反射壁でもって90度の角度に反射して光導波路の一端に入射され、光導波路の他端から出射した光は、光導波路の他方の45度傾斜反射壁でもって90度の角度に反射して光導波路基板に対して垂直に出射する。
図3及び図4は本発明の実施形態による光導波路搭載基板の製造方法を各工程順に示したものである。図3(a)は、多層の電気回路基板の断面図である。図3(a)に示した電気回路基板において、21は絶縁樹脂層、22はCuよりなる回路パターン、23はソルダーレジスト、24はソルダーランド、25は層間接続ビアないしスルーホールビア、26はFR−4等の材質から成る絶縁コア基板である。
