PURPOSE: To make it possible to align optical waveguides with each other by coupling them with each other through matching slots on individual devices.
CONSTITUTION: An optical waveguide device 30 is equipped with a through slot 42 which extends in a general direction substantially parallel to the direction of a waveguide 7 and the direction of the waveguide 7 is the same as the direction of a center axis A-A'. The through slot 42 starts at a tail end part 32 and extends properly in the optical waveguide device 30 so as to match the end point 40 of the waveguide 7. Then when the through slot 42 of the optical waveguide device 30 is coupled with the similar slot 42-1 of a similar matching device 30-1, the end parts 40 and 40-1 of the waveguides 7 come into contact with each other and the center axis A-A' or optical axis of the waveguide 7 is aligned.
