ABSTRACT:
The securing structure for optical device and fiber optics of the present invention comprises a substrate having a through hole through which a fiber optics is inserted, and an optical device secured on the plane of substrate at which the through hole opens. The substrate has a first position pattern provided in relation to the location of a through hole on the plane of substrate at which the through hole opens, while the optical device has a second position pattern provided in relation to the location of a light receiving or emitting section. The fiber optics inserted into the substrate can be coupled optically to the optical device from the positional relationship between the first and second position patterns.
According to the present invention, since the location of the through hole into which the fiber optics is inserted is identified by the first position pattern, and the location of the light receiving or emitting section of the optical device is identified by the second position pattern, it is possible to align the fiber optics and the light receiving or emitting section of the optical device by aligning the first and second position patterns.
