Abstract

PURPOSE: To provide an optical module device which is suitable for mass production and with which exact axis alignment is possible. CONSTITUTION: A resin molding type case 11 is formed of a resin. The circumference at the end of a base plate 14a of a light emitting and receiving element 14 is adhered to the case 11 by a photosetting resin 16. The bottom of the base plate 14a projected with lead pins 16b is closed by a gelatinous resin 18. Further, a thermosetting resin 19 is laminated on the gelatinous resin 18. The shrinkage strain generated in the thermosetting resin 19 is absorbed in the gelatinous resin 18 and the mounting position of the light emitting and receiving element 14 does not change in spite of the occurrence of such shrinkage strain.

2. Description of the Related Art Conventionally, this type of optical link module is
Since the module body case and the light emitting / receiving element are each made of metal, laser fusion is used to connect these components. For this fusion, the light emitting and receiving element module assembling manufacturing apparatus shown in FIG. 2 was used. A light emitting element such as a laser diode LD is mounted on the LD mounting base 1, and a module body case such as an optical module is mounted on the optical component mounting base 2. The vidicon camera 3 captures the LD beam emitted from the light emitting element attached to the LD mount 1, and the CPU 4 performs image processing on this LD beam and the image from the module main body case and displays it on the display device 5. X,
The Y and Z driving bases 6 move the LD mounting base 1 in the X, Y and Z directions so that the LD beam comes to the beam waist, and adjust the relative positions of the light emitting element and the module main body case. By this position adjustment, the light emitting element and the optical component such as the lens are aligned. When the positioning is completed, the YAG laser emitted from the laser oscillator 7 through the fiber 8 is collected by the condenser 9 and irradiated on the joint between the module main body case and each metal member of the light emitting element. By this laser irradiation, the seams of the members are fused and the module body case and the light emitting element are YAG-welded.

Is provided. The light emitting / receiving element 14 of the stopper 13
A SELFOC lens 15 is attached to the side.
The light emitting / receiving element 14 includes a base 14a and lead pins 14b, and the periphery of the base 14a is adhered to the inner wall of the resin mold case 11 by a UV curable resin 16. A ring 17 is provided on the SELFOC lens 15 side of the base 14a. The ring 17 prevents the UV curable resin 16 from dripping, and the base 14a is accurately attached to the resin molding case 11. It is positioned. In addition, a space is provided in the case 11 between the base 14a and the SELFOC lens 15 for centering. This space is temporarily sealed by closing the bottom of the base 14a from which the lead pin 14b projects with the gel resin 18. The gel resin 18 is a two-component resin that cures at room temperature. Further, the thermosetting resin 19 is laminated on the gel-like resin 18 to seal the space inside the case 11. Further, the fixing of the light emitting / receiving element 14 to the resin molding case 11 is realized by fixing the periphery of the base 14a and the lead pins 14b to the inner wall of the case 11 with each of the above resins.

In this embodiment, after the light emitting / receiving element 14 is temporarily fixed to the inner wall of the case 11 with the UV curable resin 16, the space between the light emitting / receiving element 14 and the SELFOC lens 15 is sealed. Generally, the thermosetting resin 19 has a large shrinkage ratio and a high adhesiveness. For this reason, if the thermosetting resin 19 is simply sealed, the contraction of the thermosetting resin 19 will move the position of the light receiving / emitting element 14. Therefore, even if the light emitting / receiving element 14 is positioned with respect to the case 11, misalignment occurs. However, in the present embodiment, the bottom of the base 14a is temporarily sealed with the gel-like resin 18 which is once cured at room temperature, and then the thermosetting resin 19 is sealed. Therefore, the shrinkage strain generated in the thermosetting resin 19 is absorbed by the gel-like resin 18 in the gel state when cured. Therefore, according to the structure of the optical module device according to the present embodiment, the positioned light emitting / receiving element 1 is
The inside of the case 11 can be sealed without moving the case 4.

Moreover, since the UV curable resin 16 has a quick curing property and does not apply heat as compared with other resins, it is possible to perform positioning with high accuracy. As described above, the light emitting / receiving element 14 is positioned by the UV curable resin 16, temporarily fixed by the gel resin 18, and completely sealed by the thermosetting resin 19, so that the resin is a combination of simple methods. A structure capable of canceling shrinkage strain due to curing is realized. Therefore, the relative position between the light emitting / receiving element 14 and the zirconia sleeve 12 can be controlled within the accuracy range of 0.2 to 0.3 μm, the light receiving / emitting element 14 is accurately positioned with respect to the case 11, and is placed in the optical module device. It is fixed accurately.

Further, the shrinkage strain generated in the thermosetting resin is absorbed by the gel resin. Therefore, the mounting position of the light emitting element or the light receiving element does not change even if shrinkage distortion occurs in the thermosetting resin, and the light emitting element or the light receiving element is accurately positioned with respect to the case.
