Abstract:
1. A method of producing an optical waveguide comprising the steps of: forming an optical waveguide path using a first substrate as a supporting base; securing the optical waveguide path supported by the first substrate and a second substrate using an adhesive; removing the first substrate so as to transfer the optical waveguide path to the second substrate; forming on said second substrate at least one of a light emitting element for converting an electrical signal to a light signal and a light receiving element for converting a light signal to an electrical signal; and forming on said second substrate an integrated circuit for transferring an electrical signal with said at least one of the light emitting element and light receiving element, wherein the step of forming the optical waveguide path and the step of securing the optical waveguide path and the second substrate include: wherein said second substrate comprises an electrical circuit board formed with electrical wiring, and wherein said step of forming an optical waveguide path using said first substrate as a supporting base includes: a step of forming a substrate separation layer on said first substrate so as to enable the first substrate and the optical waveguide path to be separated, a step of forming an optical waveguide path on said substrate separation layer, the optical waveguide path being formed to have an inclined surface at least at one end of the optical waveguide path.
