Optoelectronic wiring board including optical wiring and electrical wiring and method of manufacturing optoelectronic wiring device using the same

An optoelectronic wiring board comprising:

• a plurality of optical wirings formed in the same direction;
• a first dummy optical waveguide which is formed in the same direction as the optical wirings, and includes two optical waveguides which are separated from each other, the two optical waveguides facing each other at one end portion thereof, the first dummy optical waveguide radiating or scattering light, which is incident on the other end portion thereof, at the one end portion;
• optical input/output portions which are formed at each of both end portions of the optical wirings, and which input/output an optical signal to/from the optical wirings;
• an optical semiconductor device or an external light guide optically coupled to the optical input/output portions;
• and
• first dummy optical input portions which are formed at the other end portion of each of the two optical waveguides included in the first dummy optical waveguide.

A method of manufacturing a optoelectronic wiring device, comprising:

• making light incident on a first dummy optical waveguide through first dummy optical input portions;
• subjecting an image, which is acquired from the first dummy optical input portions and a vicinity thereof, to a binarizing process;
• recognizing a black part of the image, thereby detecting a position of the first dummy optical input portions;
• and
• disposing an optical semiconductor device or an external light guide on optical input/output portions of an optoelectronic wiring board, by using a result of the detection as an index.
