Abstract
An optical waveguide device of the present invention comprises: an optical waveguide including a plurality of cores configured to emit outgoing light from distal ends thereof; and a light-receiving element including a plurality of photo diodes configured to receive the outgoing light. Respective pitches Lbetween adjacent cores are greater than pitches Lbetween adjacent photo diodes. At least one photo diode on which only outgoing light of each core is incident is present with respect to each of the cores.
