Abstract
One object of the present invention is to provide a new arrangement for an optical module that enables to align the optical fiber with the semiconductor optical device in active alignment technique. The optical module of the present invention includes a container, a base and a ferrule assembly. The ferrule assembly integrates the optical fiber, the ferrule and the holder, in which the ferrule secures the optical fiber in a center thereof and the holder having a V-groove secures the ferrule in the V-groove. The container has a depression, one end of which is opened, for receiving the ferrule therein. The semiconductor optical device is mounted on a region opposite to the open of the depression of the container. Both sides of the depression are regions on a primary surface of the container, and, when the holder is placed on these two regions, the ferrule is set within the depression with gaps against side surfaces of the depression. Thus, by sliding the holder on the container, the optical fiber can be actively aligned with the semiconductor optical device mounted on the container in directions parallel to the optical axis and within the primary surface of the container.
