OPTICAL APPARATUS, PRINTED CIRCUIT BOARD

摘要

An optical apparatus includes: a semiconductor optical device integrating optical couplers, an optical element for processing a light beam associated with each of the optical couplers, and a circuit for processing an electrical signal associated with the optical element; a printed circuit board electrically connected with the semiconductor optical device, the printed circuit board including a main body and a metal piece, the main body having a first opening and a second opening, and the metal piece being held by the main body; and a first electrical component mounted on the printed circuit board. The metal piece has a first face and a second face opposite to the first face, the first opening and the second opening extend to the first face and the second face of the metal piece. The semiconductor optical device is mounted on the first face of the metal piece in the first opening.
