  • Patent number: 9586280
    Abstract: A method for manufacturing an optical module 1 includes: a cladding 12 of one end of the optical fiber is exposed; an arrangement process of arranging the optical fiber 10 such that at least a leading end of a portion on which the cladding 12 is exposed is positioned in a box portion through a pipe portion 35 in which one end is connected to the box portion 31 configured to accommodate an optical element and which extends to an outside of the box portion 31; and a soldering process of soldering an inner wall of the pipe portion 35 and the optical fiber 10 by heating at least a part of a lower region BAR interposed between a heat dissipation portion and the pipe portion 35 in a state where a part of a wall of the box portion 31, in which the optical element is accommodated, is heat-dissipated.

  • Patent number: 8777498
    Abstract: A method of the present invention is a method for manufacturing an optical module (10) including an optical fiber (3) and an optical fiber insertion pipe (2) into which the optical fiber (3) is inserted, and includes a sealing step in which the optical fiber insertion pipe (2) is hermetically sealed. The sealing step includes a contact step, a heating step, and a feeding step. In the contact step, a heat conductor member (5) is provided along and in contact with a side surface of the optical fiber insertion pipe (2), the heat conductor member having a heat conductivity greater than that of an environmental atmosphere of the sealing step and having a heat generating property of generating heat by induction heating, which heat generating property of the heat conductor member is inferior to that of the optical fiber insertion pipe (2) in terms of heat generation amount. In the heating step, the optical fiber insertion pipe (2) thus provided with the heat conductor member (5) is heated by induction heating.

  • Publication number: 20110233197
    Abstract: A method of the present invention for manufacturing an optical module is a method for manufacturing an optical module including an optical fiber and an optical fiber insertion pipe in which the optical fiber is inserted, the method including a hermetic sealing step in which the optical fiber insertion pipe is hermetically sealed, the hermetic sealing step including: a providing step in which a guide is provide to a side surface of the optical fiber insertion pipe; and a heating step in which the optical fiber insertion pipe is heated to melt a wire solder contained in the guide. As such, the method for manufacturing an optical module is provided in which the hermetic sealing is improved in performance.
