OPTICAL MODULE AND METHOD FOR MANUFACTURING THE SAME

摘要

A first opening (10) formed on a wiring board (9) and a light receiving region (13) are aligned with each other, and a light receiving element (12) is mounted on a wiring board (9). On the wiring board (9), two second openings (11) are arranged by the same process as that of the first opening (10). On an optical wiring board, two substrate marks are arranged. The substrate marks have an optical waveguide having a core (3) of the optical waveguide, and a core (5) of a dummy optical waveguide. At the time of optically coupling a light receiving region (13) and the core (3) of the optical waveguide, the opening (11) and the board marks are observed from the side of the light receiving element (12) on the wiring board (9) at the same time, and based on the observed positions, the wiring board (9) and the optical wiring board are aligned with each other. Thus, mounting assembly can be easily performed with high accuracy and mass productivity is improved.
