Abstract

PURPOSE:To easily insert an optical fiber having a prescribed outside diameter into a groove by making an adhesive material layer on the optical fiber guide groove thinner than that interposed between a groove substrate and a plate or not providing the adhesive material layer on the optical fiber guide groove. CONSTITUTION:For example, a resist used in the IC lithography process or the like is used as an adhesive material layer 3 which joins a plate 1 and a groove substrate 2, a thickness t2 of the adhesive material layer on an optical fiber groove 4 is made thinner than a thickness t1 on the other area chemically or physically by, for example, by flowing a peeling liquid dissolving the resist into the groove 4 to etch the resist layer on the groove 4. Since the thickness of the adhesive material layer on the optical fiber guide groove is made thinner that of the other area and is adjusted, even an optical fiber having slight variance of outside diameter is inserted and fixed in the groove without increasing the clearance.

There is a tendency that the thickness of the adhesive material layer in this area is larger than the thickness (tl) of the adhesive material layer in this area because the adhesive material layer sandwiched between the two areas protrudes.

However, in the optical fiber coupling member in the state shown in FIG. The adhesive material layer (2) protrudes in the direction of the optical fiber guide groove (2), and as shown in Fig. 5, the groove (the thickness of the adhesive material layer (2) on top of (4) t3) is thicker than the thickness of other areas (t1). Therefore, there was a problem that an optical fiber having a predetermined outer diameter could not be inserted into the groove (4).

(Means for Solving the Problems) The present invention provides an optical fiber coupling member that solves the above-mentioned problems, and is characterized by the adhesive material layer interposed between the groove substrate and the plate. This is because the thickness of the adhesive material on the optical fiber guide groove is small relative to the thickness, or there is no adhesive material layer on the optical fiber guide groove.

As shown in the figure, as the adhesive material layer (■) that joins the plate (1) and the grooved substrate (■), a resist used, for example, in the IC phosphorography process, is used, and the optical fiber guide groove (peeling method that dissolves the resist in the field) is used. Chemically or physically, such as by flowing a liquid to erode the resist layer on the top of the groove (4), the groove (thickness t2 of the adhesive layer on the top) is made smaller than the thickness of other areas (tl). It consists of

(Function) The configuration shown in Figure 2 avoids the conventional problem of difficulty in inserting an optical fiber with a predetermined outer diameter due to the swelling of the adhesive substance Jim (3) at the top of the optical fiber guide groove (4). In addition, by adjusting the thickness of the adhesive material layer located on the top of this groove (4), groove (2) can be formed.

Since there is no adhesive layer (■) on the upper part of the groove (2), it has the effect of preventing dust from adhering to this area. (2) There will be no snags when inserting the optical fiber into the interior, and the optical fiber can be inserted smoothly.

In addition, in the conventional process of recognizing the cross-sectional shape of an optical fiber guide hole and measuring the hole position, the shape is determined by inputting transmitted light parallel to the longitudinal direction of the groove and projecting the groove shape by the transmitted light on the output side. However, if there was dust attached to a part of the groove inner wall, the shape of this dust would be projected as is, making it impossible to recognize the exact groove shape. However, by adopting the configuration shown in FIG. 3, it has become possible to recognize the groove shape with high precision in order to suppress the adhesion of dust within the groove as much as possible.

The thickness of the adhesive material layer (3) is approximately 1 μm, and in order to form such a thin adhesive material layer (J), a material with considerably low viscosity is required.
A resist used in an IC phosphorography process and the like was used. The plate (1) was a silicon plate with a wall thickness of 0.5 mm, and the groove substrate (2) was a silicon plate with a wall thickness of 1.5 mI+.

(Effects of the Invention) According to the above-described optical fiber coupling member of the present invention, the thickness of the adhesive material layer on the upper part of the optical fiber guide groove is made thinner than in other areas, and by adjusting the thickness, the adhesive material layer can be slightly removed. Even optical fibers with varying diameters can be inserted and fixed in the groove without increasing the clearance.

In addition, by removing the adhesive layer on the top of the optical fiber guide groove, it is possible to prevent dust from adhering to the groove, and as a result, there are fewer irregularities caused by dust, making it easier to insert the optical fiber into the groove. It is possible to perform the recognition of groove-shaped folds with high precision using this method.

Furthermore, since there are some gaps in the bonding surface between the plate and the grooved substrate where no adhesive material layer exists, it is possible to connect the plate and groove by replenishing the gaps with a material with high adhesive strength when inserting the optical fiber in the subsequent process. The bonding force with the grooved substrate can be further increased.
