脂肪鎖変性エポキシ樹脂(DIC社製、EPICLON EXA-4816)80重量部、脂環式エポキシ樹脂(ダイセル社製、EHPE3150)20重量部、光酸発生剤(アデカ社製、SP170)2重量部、乳酸エチル(武蔵野化学研究所社製、溶剤)40重量部を混合することにより、アンダークラッド層およびオーバークラッド層の形成材料を調製した。
o−クレゾールノボラックグリシジルエーテル(新日鉄住金化学社製、YDCN−700−10)50重量部、ビスフェノキシエタノールフルオレンジグリシジルエーテル(大阪ガスケミカル社製、OGSOLEG)50重量部、光酸発生剤(アデカ社製、SP170)1重量部、乳酸エチル(武蔵野化学研究所社製、溶剤)15重量部を混合することにより、コアの形成材料を調製した。
上記形成材料を用い、厚み25μmの帯状(幅0.1mm)のアンダークラッド層の表面の中央に、その長手方向に沿って、厚み50μmの帯状(幅50μm)のコアを1本形成し、このコアを被覆するように、上記アンダークラッド層の表面に、オーバークラッド層(コアの上面からの厚み25μm、幅0.1mm)を形成した。これにより、厚み0.1mm、幅0.1mmの線状の第1および第2光導波路を得た。
発光素子として、ULM Photonics社製のULM850-05-TT-C0101G を準備し、第1電気基板に実装した。この発光素子の寸法は、第1電気基板を含めて、幅W0が1.0mm、厚みT0が0.3mmであった。また、受光素子として、京セミ社製のKPDG006HA1を準備し、第2電気基板に実装した。この受光素子の寸法は、第2電気基板を含めて、幅W0が1.0mm、厚みT0が0.35mmであった(図12,図13参照)。
