Patent ID: 7565043

Claim:
An optical module comprising, on the same optical waveguide substrate: a light-emitting element; a first optical waveguide optically coupled to the light-emitting element; a light-receiving element; and a second optical waveguide guiding optical signals to the light-receiving element, wherein the light-receiving element is arranged in a position where an optical axis of the light-emitting element and a normal to a light-receiving surface of the light-receiving element are not in a same plane, and comprises optical path conversion means that guides optical signals propagating along the second optical waveguide to the light-receiving surface of the light-receiving element, and ensures that an image of the light-emitting spot of the light-emitting element projected onto a plane comprising the light-receiving surface of the light-receiving element does not overlap with light-receiving surface of the light-receiving element.
