Abstract
PURPOSE:To inhibit misalignment generated at the time of welding, and to contrive to realize an optical transmission module for a single mode optical fiber, by fixing the junction of a stem and an optical fiber holding member by welding, in a state that both of them are positioned and fixed by a mechanical constraining method. CONSTITUTION:At the time of bringing an optical fiber holding member 7 to resistance welding to the bottom face of a stem 2, the holding member 7 is pressurized in the vertical direction against the bottom face of the stem 2 by a pressure piston 11, and a foot of the holding member 7 is pressed against the bottom face of the stem, and as a positioning and fixing method in that case, the fixation is executed by providing a screw hole on the side face of the pressure piston 11, and pressing the holding member 7 against the inner wall of the pressure piston 11 by a screw 12. That is, at the time of welding the optical fiber holding member 7 and the bottom face of the stem 2, as for the holding member 7, a part of its foot bottom is melted by high heat, and it goes to free in the parallel direction against the stem 2, but the holding member 7 is pressed against the inner wall of the pressure piston 11. In such a way, misalignment in the parallel direction is suppressed.
