Optical waveguide, optical wiring member, and method of mounting optical device on optical wiring member

An optical wiring member, including:

• a substrate on which a light-emitting device and a light-receiving device are mounted;
• and
• an optical waveguide comprising a communication optical waveguide core and an optical waveguide clad that entirely covers said communication optical waveguide core, in order to transmit communication light between said light-emitting device and said light-receiving device, said optical waveguide being mounted on said substrate, wherein
• said optical waveguide is equipped with a position-aligning light guiding portion for introducing position-aligning light into said communication optical waveguide core.

A method of mounting an optical device on an optical wiring member, said optical wiring member including:

• a substrate on which, as said optical device, at least one set of light-emitting device and light-receiving device are mounted;
• and an optical waveguide comprising a communication optical waveguide core and an optical waveguide clad which entirely covers said communication optical waveguide core in order to transmit communication light between said light-emitting device and said light-receiving device, said optical waveguide being mounted on said substrate, wherein:
• said optical waveguide is equipped with a position-aligning light guiding portion for introducing position-aligning light into said communication optical waveguide core;
• and
• at least either said light-emitting device or said light-receiving device is positioned by using, as a target light, position-aligning light which is introduced from said position-aligning light guiding portion into said communication optical waveguide core and exits from said substrate.
