Abstract: PURPOSE:To obtain high coupling efficiency between an optical semiconductor element and an optical fiber by inserting the optical fiber into a guide opposite to the optical semiconductor element, and fixing it to a stem at a position which is <=2mm. away from the tip of the guide. CONSTITUTION:The tip of the optical fiber 6 which is inserted into the fiber guide 9 and fixed projecting by a proper extent is positioned at a proper interval from the optical semiconductor element 5. Then, the guide 9 is deformed plastically for such an adjustment that light from the optical semiconductor element 5 is incident on the fiber 6 to a maximum quantity, and then a fixing material 7 is fixed to the position of the projection part 10 of a pedestal 3. The flexural rigidity of the guide 9 is much larger than that of the fiber 6, so it is not influenced by the setting contraction of the fixing material 7. Therefore, the material is fixed after the optical axis is aligned, so its precision is improved and the assembly yield and reliability are also improved.
