| 英文摘要 | PURPOSE:To enable fine adjustment of a position in the three directions of X, Y, Z while monitoring optical axis alignment, to reduce variations in coupling efficiency with optical fiber and to improve mass producibility by attaching a plate with a lens to a cap. CONSTITUTION:A heat sink 2 is assembled on a stem 6 so that a light emitting point of an LD chip 1 is subjected to alignment with a center axis of the stem 6. A cap 8 is provided with a plate 10 having a lens through a brazing material 9. Fine adjustment is performed to the cap 8 in the directions of X, Y making an LD emit light, optical axis alignment is monitored by a photodetector which is provided in opposition to a plate 3 equipped with a lens, and the cap 8 is fixed at a position whereon optical axis in the directions of X, Y is aligned. The brazing material 9 between the cap 8 and the plate 10 equipped with a lens is fused through heat up fixing the cap 8 in the directions of X, Y. Optical axis alignment state in the direction of Z axis is monitored, optical axis is aligned, cooling is applied, and the plate 10 with a lens is fixed. Coupling efficiency with optical fiber can be improved in this way. |
