    • The present invention relates to a process for producing an optical waveguide, including the steps of applying a cladding layer-forming resin onto a substrate and curing the resin to form a lower cladding layer; laminating a core layer-forming resin film on the lower cladding layer to form a core layer; subjecting the core layer to exposure to light and development to form a core pattern; and applying a cladding layer-forming resin over the core pattern to embed the core pattern therebeneath, and curing the resin to form an upper cladding layer, wherein the step of forming the core layer includes the steps of (1) allowing the core layer-forming resin film to be temporarily attached onto the lower cladding layer using a roll laminator, and (2) thermocompression-bonding the temporarily attached core layer-forming resin film onto the lower cladding layer under a reduced pressure. There is provided the process for producing an optical waveguide having a uniform core with a good productivity.
    • 本发明涉及一种光波导的制造方法,其特征在于,包括以下步骤:在基板上涂布包层形成树脂,使树脂固化形成下包层; 在下包覆层上层叠芯层形成树脂膜以形成芯层; 对芯层进行曝光和显影以形成芯图案; 以及在所述芯图案上涂布包层形成树脂以在其下方嵌入所述芯图案,并使所述树脂固化形成上包层,其中形成所述芯层的步骤包括以下步骤:(1) 使用辊式层压机将树脂膜暂时附着在下敷层上,(2)在减压下将临时附着的芯层形成树脂膜热压接在下包层上。 提供了具有均匀核心的具有良好生产率的光波导的制造方法。
