Polyimide optical waveguide |
| abstract |
An optical waveguide is produced by forming on a substrate a waveguide layer and/or a clad layer containing, as their main ingredient, polyimide with a fluorine substitution rate of 30% or higher (thus as a fluorinated polyimide layer), with a primer layer laid in between that contains, as its main ingredient, polyimide with a fluorine substitution rate of 10% or lower (including 0%). This improves adherence of the fluorinated polyimide layer to the substrate and prevents the fluorinated polyimide layer from peeling off the substrate. For more effective prevention of such peeling-off and of warping of the substrate, the primer layer is preferably formed to have a thickness of 0.1 to 20 mum. The primer layer may contain a coupling agent. |
