とが出来る。(Function) In the optical fiber holder constituting the optical fiber terminal of the present invention, the end surface of one end of the tubular member, which is the optical fiber insertion portion, is inclined with respect to the central axis of the tubular member. Therefore, when inserting the optical fiber into the tube of the tubular member, the tip of the optical fiber can be slid along the inclined surface of one end of the tubular member.
このため、光ファイバの光軸と管状部材の中心軸が一致

を有している。Furthermore, an optical fiber is arranged within the groove of the fiber arrangement member provided with at least one groove. The groove has a center plane located approximately at the center between both side wall surfaces of the groove, which substantially encompasses an axis extending from the central axis of the tubular member, and has a dimension that is substantially equal to the outer diameter of the cladding of the optical fiber at least in part thereof. It has a groove width of .
この構成で、光ファイバの光軸は、既にその両側壁面に

出来る。Since the outer wall of the cladding part of the optical fiber is in contact with the wall surfaces on both sides, the tip of the optical fiber is fixed in the direction perpendicular to the wall surface and slides along the inclined surface, and the optical axis of the optical fiber is easily aligned with the wall surface of the tubular member. Match the center. Thereby, the optical fiber can be easily inserted into the tube of the tubular member even if the optical axis of the optical fiber and the central axis of the tubular member do not coincide.

It is sandwiched between two glass plates 3-1 and 3-2 with a thickness of 500 pm. Further, an end surface 6 at one end of the tubular member 2, which is the insertion portion 5 for the optical fiber 4 having an outer diameter of 12511 m, is inclined at an angle of about 45 degrees with respect to the central axis of the tubular member 2.

The pitch formed in the fiber array member 7 of m is 250 yen 1
They are arranged in the four grooves 8 of m. FIGS. 1(b) and 1(e) show a side view and a plan view of the fiber array member 7 viewed from the direction of arrow A and from the direction of arrow B, respectively. The minimum groove width of the groove 8 is set to 130 μm, which is about the same as the optical fiber outer diameter of 125 pm, so that both side wall surfaces 9-1, 9-2 are in contact with the cladding portion of the optical fiber 4. Further, when the optical fiber 4 is inserted into the tube of the tubular member 2, it becomes arched, so the shape of the wall surface 9-3 in the plane perpendicular to both side wall surfaces 9.1.9-2 is semi-arc-shaped. . Further, both side wall surfaces 9 are provided so that the optical fiber 4 can be easily placed in the groove 8.
-1.9-2 is also semi-arc shaped, and the fiber array member 7
The groove width on both end faces of the optical fiber 4 is set to approximately 150 pm, which is sufficiently larger than the cladding diameter of the optical fiber 4. Furthermore, the fiber array member 7 and the optical fiber holder 1 are arranged so that the optical axis of the optical fiber 4 is aligned with the central axis of the tubular member 2 within a central plane located approximately at the center between the wall surfaces 9-1 and 9-2. They are placed on a ceramic stand 10 so that they match. Note that the grooves 8 can be easily formed by machining.

This will be explained using (d). Here, the inner diameter of the tube of the insertion section 5 (broken line in the figure) increases in a tapered manner toward the end surface 6, and the tube inner diameter at the end surface 6 is approximately 150 pm, which is sufficiently larger than the cladding diameter of the optical fiber.

とにより容易に形成される。The method for forming this tapered portion is to fill an aqueous solution into the tube of a tubular member 2 whose outer wall is coated with a resist or the like, and to immerse one end of the tubular member 2 in an etching solution. This causes a concentration difference in the etching liquid that has permeated the inner wall of one end, and the inner wall of the tube at one end, which is the insertion section 5, is etched into a tapered shape. Further, the inclined surface 6 can be easily formed by obliquely polishing one end portion which has been etched into a tapered shape.

As mentioned before, the optical axis of the optical fiber already coincides with the central axis of the tubular member in a plane parallel to both side wall surfaces of the groove 8, and both side wall surfaces 9-1, 9-2 are aligned with the optical fiber 4. It is configured to be in contact with the cladding part of the The tip of the optical fiber 4 is fixed in a direction perpendicular to the wall surface and floats along the inclined surface 6. By this, the optical axis of the tip of the optical fiber 4 can be easily aligned with the central axis of the tubular member 2, and the tip of the optical fiber 4 can be easily aligned with the central axis of the tubular member 2. It can be inserted into the tube. Then the second
