ことが重要である。2. Description of the Related Art In an optical communication system, a large number of laser elements such as a semiconductor laser element for a light source for emitting signal light and a semiconductor laser for pumping an optical amplifier for amplifying signal light are used. These laser elements are lasers. In an optical component module such as a module, it is coupled with an optical fiber that is an optical transmission line. In order to increase the amount of light output from the laser module, it is important to use a high-power laser element and increase the coupling efficiency between the laser element and the optical fiber.

い。Since the output light from the laser element spreads at a constant angle, it is necessary to use a condenser lens to increase the coupling efficiency with the optical fiber. As a condenser lens,
One or two aspherical lenses may be used, a ball lens may be used, or more conveniently, a spherical fiber may be used. In addition, in order to obtain high coupling efficiency, it is preferable to use one or more aspherical lenses.

【０００４】ところで、数１０％以上の高い結合効率を
得るためには、レーザ素子と集光レンズと光ファイバと

る。By the way, in order to obtain a high coupling efficiency of several tens of percent or more, it is necessary to fix the laser element, the condenser lens and the optical fiber at a highly precise mutual position of 1 μm or less.

ＹＡＧレーザ光等の高出力光により光学部品保持材同士

材同士を接合するものである。To fix the optical component holding members constituting the optical component module to each other, welding with a high-power solid-state laser light source such as a YAG laser element is often used. This is for joining the optical component holding materials by melting and then solidifying the optical component holding materials with a high output light such as YAG laser light.

には引っ張り力に伴う浮き上がりなどがある。However, the beam diameter of YAG laser light is 1
Since the diameter is not less than 00 μm, the optical component holding material is displaced by about several μm when it solidifies. In order to realize high coupling efficiency, this positional shift must be suppressed. The causes of the positional deviation due to welding include a tensile force due to the surface tension during solidification, and a lift due to the tensile force when there is a gap between the optical component holding materials.

Japanese Patent Laid-Open No. 3 proposes a method in which optical component holding materials are previously bonded with an adhesive and then the optical component holding materials are welded and joined.

ずれ量が増大するという問題は解決できない。However, in order to firmly join the optical component holding members to each other, it is necessary to increase the output of the laser beam for welding. The melted portion becomes large, and the positional deviation due to the shrinkage of the melted portion increases. Therefore, in the case of using the method of forming a thin portion as in the former case, when trying to secure a large bonding strength with a strong laser beam, the amount of shrinkage of the melted portion increases, and the amount of positional deviation accordingly. The problem of increase cannot be solved.

When the intensity of the laser light increases, the first and second welded
In the x-axis direction or the y-axis direction, the shrinkage amount of the welded part during solidification differs due to the difference in thermal expansion coefficient and shape due to the difference in the material of the optical component holding materials and the heat distribution in the optical component module. Because pulling force acts on x
Positional displacement occurs in the axial direction or the y-axis direction. Further, when the intensity of the laser light increases, a tensile force due to contraction is generated on the surface side of the welded portion during solidification, so that the first optical component holding member 11 and the second optical component holding member 11 as shown in FIG. It is presumed that the side of the joint 12 opposite to the joint moves away from each other with the joint serving as a fulcrum, which causes a displacement in the z-axis direction. In this way, when welding is performed with a strong laser beam to increase the joint strength,
Positional deviations in the x-, y-, and z-axis directions occur and the reliability of the optical coupling strength of the optical component module decreases.

The intensity of the laser beam during the second welding is shown in FIG. The results of measurement with parameters are shown. FIG.
As is clear from the above, it can be seen that the amount of positional deviation substantially depends on the light intensity during the first welding and does not depend on the intensity of the laser light during the second welding. Further, it is clear that the bonding strength depends on the strength of the laser beam at the time of the second welding.

Specifically, when the optical coupling efficiency before welding is 100, the optical coupling after welding is performed. The intensity of the laser light is preferably such that the efficiency is about 97 to 98 or more. As described above, when the loss of the optical coupling efficiency after welding is set to about 2 to 3%, the positional deviation amount is within 1.0 μm.

It is preferable that the intensity of the laser beam during the first welding is twice or more.
