Beschreibung
Zusammenfassung:	An optical apparatus includes: a semiconductor optical device integrating an optical coupler, an optical element, and an electrical circuit; and a printed circuit board including a main body and a metal piece. The body has first and second openings. The first opening, the metal piece and the second opening are arranged in a direction of a first axis. The first and second openings extend from the front and back faces of the body along the direction to the first and second faces of the metal piece, respectively. The metal piece is supported by the body. The semiconductor optical device is mounted on the first face of the metal piece in the first opening. The body has a supporting face connecting the first side of the first opening with the second side of the second opening and supporting the second face of the metal piece in the first opening.
