Abstract:
1. A process for producing a polymer optical waveguide comprising: 1) preparing a rubber mold by bringing a rigid substrate, having a rubber layer-forming concave portion, into close contact with a core master template, wherein the core master template comprises a convex portion; filling a rubber-mold forming curable resin between the rigid substrate, with which the core master template has been brought into close contact, and the core master template, wherein the rubber mold has a composite layer structure wherein a rubber layer which has a concave portion corresponding to an optical waveguide core and comprises the rubber mold-forming curable resin is buried in the rubber layer-forming concave portion of the rigid substrate having the rubber layer-forming concave portion; 2) bringing a cladding substrate into close contact with the rubber mold; 3) filling the concave portion of the rubber mold, with which the cladding substrate has been brought into close contact, with a core-forming curable resin; 4) curing the core-forming curable resin filled into the concave portion of the rubber mold; 5) removing the rubber mold from the cladding substrate; and 6) forming a cladding layer on the cladding substrate on which the core has been formed.
