| 英文摘要 | A method of manufacturing an optical module for wavelength-division multiplex optical transmission, which module comprises a first optical fiber having a first port at its one end and a second and a third optical fiber fused to the first optical fiber at its side face such that the first optical fiber is positioned in the center between the second and third optical fibers. The manufacturing method comprises a first step of regulating the aspect ratio at the fused portion while heating the fused portion and elongating the fused portion at zero speed or a very low speed and a second step of regulating the coupling length of the fused portion while elongating the fused portion at a higher speed than in the aspect ratio regulating step under the conditions of the heating temperature of the fused portion lowered and the aspect ratio kept unchanged. |
