Abstract:
An optical transmission device includes: a substrate; a waveguide that is provided in the substrate and transmits an optical signal; a signal wiring that is provided in the substrate and transmits an electric signal; and a silicon wiring that is provided in the substrate and is silicon added with an impurity. The signal wiring is placed in an area of the substrate, the area being away from an end of the substrate by a predetermined distance or more. One end of the silicon substrate is connected to the signal wiring, and the other end of the silicon wiring extends to the end of the substrate.
