調整を行なうのである。In this embodiment, first, as shown in FIG. 1a, the holder 10 is
The lens or ferrule 11 is inserted and defined by processing with a loose precision of about 00 μm. In this state, the machining accuracy of the holder 10 is low, so that the optical axis of the inserted and fixed lens or ferrule is misaligned with the center line of the holder. Therefore, as shown in Figure 1, a light source 13, a power meter 1
4 and a polishing jig 17 having a polishing wheel 16 that rotates parallel to the optical axis 15 of the holder 10 and the optical axis of the lens or ferrule 11 of the lens or ferrule 11.
7, and polish the portions (portions A) of the two adjoining surfaces IQa and 10b of the holder 10 that are deviated from the optical axis to the polishing reference surface 18. Next, as shown in FIG. 1a, the holder 10 is placed on the substrate 12 provided with the reference surfaces 12a and 12b so that one polished surface 10a is in contact with the substrate 12, and the other polished surface 10b is Abut against the reference surface 12a or 12b, and in that state, holder 10
The adjustment is made by sliding the light in the direction of its optical axis to achieve the best optical coupling.
