定な光ファイバアレイを提供することを目的とする。In the conventional optical fiber array, as shown in FIG. 4, the optical fiber 2 is in contact with the V-groove side wall at two points and at the holding plate 3 at one point. Normal V
Since the groove block 1 and the pressing plate 3 are made of a material such as ceramic or glass that has high rigidity and is hard to be deformed, there are the following problems. (1) Since the top of the V groove is a notch, when an external force is applied in a polishing process or the like, cracks 8 are likely to occur as shown in FIG. In the conventional optical fiber array, an external force applied to the pressing plate 3 is transmitted to the V groove portion via the optical fiber 2 and a crack is frequently generated. (2) Generally, when the adhesive 4 is cured, it is accompanied by volume contraction,
Moreover, in the optical fiber array illustrated in FIG. 4, since the V-groove block 1 and the pressing plate 3 have high rigidity, the shrinkage force of the adhesive 4 remains as an internal stress of the cured adhesive resin.
As a result, when the optical fiber array is exposed to a temperature change or a high humidity environment, the internal stress causes a problem that the interface between each of the V-groove block 1, the optical fiber 2, and the holding plate 3 and the adhesive is separated. An object of the present invention is to solve the above-mentioned drawbacks of the prior art and to provide an optical fiber array which is stable even under an external force and a severe temperature and humidity environment.

フィルムは必ずしも必要ではない。1 is a cross-sectional view of an optical fiber array according to an embodiment of the present invention. The V-groove block 1 is formed by grinding four V-grooves on a quartz glass block, and the holding plate 3 is obtained by polishing a quartz glass plate in a plane. The four-core optical fiber 2 is in contact with the V-groove wall surface of the V-groove block 1 adhered and fixed by the first adhesive 4a, but is not in direct contact with the holding plate 3, and the second adhesive of 10 μm is interposed therebetween. A resin layer formed of the agent 4b is formed. An example of the method of manufacturing the optical fiber array of the present invention will be described with reference to FIG. First, the optical fibers 2 are arranged in the V-grooves of the quartz glass V-groove block 1, the first adhesive 4a is dropped from the upper portion, the non-adhesive film 5 is placed thereon, and the flat plate 6 is placed and pressed. At this time, the dropping of the first adhesive 4a may be omitted.
Next, the first adhesive 4a is permeated from the end surface of the V-groove block, and the first adhesive 4 is inserted into the gap between the V-groove block 1 and the flat plate 6.
Fill a. In this embodiment, an ultraviolet curable epoxy resin is used as the first adhesive 4a and a polyethylene film is used as the non-adhesive film 5. A light-transmissive glass plate was used as the flat plate 6. In this state, the glass flat plate 6
The first adhesive 4a was cured by irradiating it with ultraviolet rays from above. After the adhesive is hardened, the flat plate 6 and the non-adhesive film 5 are removed, the second adhesive 4b is applied again to the removed surface, the holding plate 3 is placed, and the second adhesive 4b is hardened. The resin layer formed by curing the second adhesive 4b serves as a buffer layer against external force. Where the first adhesive 4
Although a is not necessarily limited to the ultraviolet curable type, the ultraviolet curable type adhesive is the most suitable adhesive for the production of optical fiber arrays and the like because it cures quickly and has excellent productivity. Further, the second adhesive 4b for adhering the pressing plate 3 in the subsequent step may be the same as or different from that used in the previous step. According to the manufacturing method of the present invention,
A resin layer can be formed between the optical fiber 2 and the pressing plate 3 when the pressing plate 3 is bonded in a later step. The thickness of the resin layer can be adjusted by the pressing pressure of the pressing plate 3 and the time from application of the adhesive to curing. Further, according to the manufacturing method of the present invention, when the optical fiber 2 is bonded to the V groove block 1, the first
Even when the curing shrinkage of the adhesive 4a occurs, it is possible to form the void 7 at the interface with the non-adhesive film 5 as shown in FIG. Further, as shown in FIG. 3B, the non-adhesive film 5 may be deformed in accordance with the curing shrinkage of the first adhesive 4 a, and a space 7 may be formed between the non-adhesive film 5 and the flat plate 6 on the upper side. Therefore, the residual stress in the resin after the curing of the first adhesive 4a can be suppressed smaller than in the conventional case. The end-face polishing was carried out for each of the four-core optical fiber array manufactured as described above and the conventional optical fiber array of 100, and the frequency of crack generation at the top of the V groove was examined. As a result, 32 cracks were found in the conventional optical fiber array, whereas only 3 cracks were found in the optical fiber array according to the present invention. Further, a high temperature and high humidity test at 70 ° C. and 95% RH for 400 hours was carried out on each of 100 similar optical fiber arrays, and the number of peeled adhesives, V groove blocks, holding plates and optical fibers was examined. As a result, peeling was observed in 65 pieces in the conventional optical fiber array, whereas only 5 pieces were peeled in the optical fiber array according to the present invention. The non-adhesive film 5 used in this example is flexible and thin so that it can be deformed in shape as shown in FIG. 3B according to the curing shrinkage of the first adhesive 4a. Film may be used. In this case, the non-adhesive flat plate 6 is used, and in the second step, only the upper flat plate is removed and the holding plate is adhered onto the adhesive film. The optical fiber array manufactured by this method can also achieve the same effect as the above-mentioned example.
As the flat plate 6 of the embodiment, any plate-shaped member can be used as long as it can press the optical fiber 2 and position it correctly in the V groove, and at least the contact surface is a non-adhesive plate-shaped member. In some cases, the non-adhesive film 5 or the adhesive film is not always necessary.

It is possible to prevent cracking at the top. Further, by manufacturing the optical fiber array by the method of the present invention, the residual stress due to the curing shrinkage of the adhesive is small, and the adhesive does not peel off even in a severe environment such as high temperature and high humidity and the stable performance is maintained for a long time. can do.
