ABSTRACT:
A sub-assembly containing an optical element and having a holder portion into which a ferrule that is attached to the end portion of an optical fiber can be inserted with sufficient gap, an electronic circuit electrically connected to the optical element, and a lead frame are molded with a transfer mold resin to produce a molded sub-assembly. The ferrule is inserted into the holder portion of the molded subassembly, and the optical coupling efficiency between the optical fiber and the optical element is adjusted while moving the ferrule in the ferrule insertion direction, a direction perpendicular thereto or by rotating the ferrule.
