合器。[Claims for Utility Model Registration] A package having a first mounting hole on a side surface, an optical fiber fixed in the first mounting hole, and a heat dissipating package fixed in the package and equipped with a semiconductor laser element. a header, a weldable sleeve fixed near the header in the package and having a through hole, and a lens inserted into the through hole for optically coupling the semiconductor laser element and the optical fiber therein. An optical coupler comprising a cylindrical weldable lens holder, the optical coupler having a horizontal portion fixed to the bottom surface within the package, and a second mounting hole provided substantially perpendicular to the horizontal portion. A header carrying the semiconductor laser element is fixed on the horizontal part of the base having a weldable vertical part, and after adjusting the optical axis of the lens holder inserted into the through hole with respect to the semiconductor laser element. welding to the sleeve and attaching the sleeve to the second sleeve.
An optical coupler characterized by being welded around the mounting hole.
