Then, the input side optical fiber component 65 is fixed to the face-to-face position by pressing it against the inner wall (see FIG. 1C).

After the surfaces are aligned by the surface alignment mechanism 57F in this way, a predetermined gap is opened by Z-axis feed to perform coarse alignment. Here, the condition for coarse alignment is the search range 200 μ
The standard dimensions are m square, feed pitch 3 to 5 μm, and gap 100 μm.

In the coarse alignment, light is sent from the LD light source 67 to the input side optical fiber component 65, and the amount of this light incident on the image fiber 73 through the optical circuit component 9 is converted into light voltage into O / E. It is input to the personal computer 63 via the converter 71, and each axis is automatically controlled until the light amount reaches a desired level.

When the coarse alignment is completed, fine alignment is performed to further improve the accuracy. The condition of this fine adjustment is the search range
30-40 μm square, feed pitch 0.1 μm, gap 10 μm
Is the standard.

First stage 5F and second stage 5S
When the fine alignment is completed, the connection is continued.

The connection procedure will be described below.

First, the W-axis moving mechanism 75 is controlled to align the dispenser nozzle 91 with the gap between the input side optical fiber component 65 and the optical circuit component 9 or the gap between the optical circuit component 9 and the output side optical fiber component 69. And dispenser nozzle 9
The UV adhesive in 1 is dropped into the gap. At this time, the image displayed by the CCD cameras 95, 95 can be checked and confirmed.

After applying the adhesive, the W-axis moving mechanism 75 is controlled to position the UV irradiation light heads 97, 97 mounted on the slider 83 on the connection surface, and then ultraviolet rays are irradiated to dry the adhesive. Let it stick.

The connection is performed as described above, but when the optical circuit component 9 is changed, the length and the width are changed, and accordingly, the stroke of the CCD camera 95 and the UV irradiation light head on the W axis are adjusted accordingly. The intervals and strokes of 97 and 97 are appropriately changed.

From the above results, axis alignment and further connection can be performed accurately.

Further, since the spherical seat 105 for holding the input side optical fiber part 65 and the output side optical fiber part 69 is balanced and held by the spring 109 in a state of being suspended in the air, the end faces can be held with a slight pressing force. Optical circuit component 9
Can be brought into contact with the end face of the to make face-to-face matching. Further, the state of the connection surface can be confirmed on the screen.

The present invention is not limited to the above-described embodiment, but can be implemented in other modes by making appropriate changes. That is, although the springs 109F and 109S are used as the elastic bodies, the springs 109F and 109S for maintaining the balance are
Optical fiber parts 65 and 69 held by 05F and 105S
Since the behaviors of the spherical seats 105F and 105S change depending on the weight and the like, it is necessary to use an optimum spring constant.
