The outer diameter axes of the left and right optical fibers to be fused are almost aligned with each other by inserting the optical fiber on a multi-core fixed V-groove base on which a V-groove for mounting and fixing the optical fiber is precisely processed in a straight line. Due to the surface tension acting on the optical fiber during discharge heating, the core axes of these left and right optical fiber core wires are aligned.

That is, this is provided with a slope of approximately 45 degrees that serves as a V groove for mounting each optical fiber 101, is finely held by the guide member 100 fixed in a stationary state, and is a pair of movable members that interlock with the stack type piezoelectric element. Parts 102A, 102
The movable parts 102A and 102B are provided with a plurality of pairs of Bs.
The optical fiber 101 is finely adjusted in various directions to align the optical fiber 101 by a combination of vertical fine movements.

In the case of the SM type of 5 μm, the thickness of each movable part is 10 because the thickness of the guide member between the movable parts needs to be taken into consideration.
It should be 0 μm or less. However, it is difficult to improve the processing accuracy for such a thickness of the order of several tens of μm, and it is very easy to break and easily bent, so that the assembling work is also difficult.

Have been proposed. In this aligning device, for example, in the case of an SM mode optical fiber having an outer diameter of 125 μm, since the thickness of the movable part that presses the optical fiber is about 180 μm, the workability of the end face is easier than that of the previous one. In addition, problems such as cracking and difficulty in assembly are reduced.

There is a problem that the optical fiber is misaligned. Therefore, in view of the above-mentioned problems, the present invention has an advantage that the planar processing is easy, the handling and the assembling workability at the time of assembling are improved, and the aligning state of the adjacent optical fibers is not adversely affected. Furthermore, it is an object of the present invention to provide an optical fiber aligning device that can perform highly accurate aligning work.

An optical fiber aligning device for aligning, wherein the V groove is
A piezoelectric element, which is composed of a fixed portion and a movable portion, is arranged so that the fixed portion and the movable portion face each other between both facing V grooves on both sides of the base, and the movable portion is a centering drive source.

Since the movable parts and the movable parts are arranged alternately, the movable parts are not separated from each other independently and separately and are not adjacent to each other, and the movement of the movable parts in each V groove does not occur in the adjacent V grooves. The aligning device is not affected. Further, between the pair of V-grooves facing each other on both sides of the base, the fixed part and the movable part are alternately arranged so as to face each other. Nevertheless, if the whole centering device is used, a positive centering means in both directions can be configured.

In other words, the movable portions 2 are arranged such that the piezoelectric elements are shifted so as not to overlap each other, and are individually connected to the piezoelectric elements 3 via the mounting members 4 having a predetermined span.

Is a well-known stack type that expands and contracts in the lengthwise direction by several μm to several hundreds of μm depending on the applied voltage, and is attached to one end side of each plate-shaped mounting member 4 as shown in FIG. Each movable portion 2 is attached to the end surface on the other end side. The movable portions 2 are arranged in such a direction that the displacement direction of the stack-type piezoelectric element when a voltage is applied matches the height change of the movable portion 2. On the other hand, since each piezoelectric element 3 is integrally and individually connected to each movable portion 2 on the base 1 side by the plate-shaped mounting member 4, the movements of the piezoelectric element and the movable element match, and the applied voltage Piezoelectric element 3 caused by changes
By the expansion and contraction displacement, the height of each movable portion 2 in each groove 6 can be individually and arbitrarily changed. Note that, in FIG. 1, the piezoelectric elements and the like of the side portion 1C are omitted in order to clarify the mounting state of each portion, but these configurations are similar to those of the side portion 1A.

こすおそれが非常に少なくなる。On the other hand, in the opposing V-shaped groove 7 provided on the opposite side of the base, the arrangement of the fixed portion 5 and the movable portion 2 is opposite to that shown in FIG. The optical fiber 8 on the other side is pressed against the +/- Y direction and the -X direction (obliquely leftward on the paper) while contacting the sides 5A, 2A of the V groove 2 with respect to the movement of the movable portion 2 in the +/- Y direction. Be moved. After all, the pressing movement direction of the optical fiber 8 placed in the V groove on one side is + X direction, and the pressing movement direction of the optical fiber 8 on the other side is only -X direction, but it is This makes it possible to align the pair of optical fibers 8 in the +/- X direction. In addition, a fixed part 5 is provided between the movable parts 2.
Are arranged, and the movable parts are separated independently and separately from each other, so that adjacent parts do not come into contact with each other or slide. Therefore, even if the V-grooves have different centering amounts, it is very unlikely that the centering operations of the adjacent V-grooves interfere with each other to cause misalignment.

It is preferable to form (45 ° on each side), but when the arrangement pitch of the optical fibers is fine, it may be narrower (for example, about 30 °).

のである。FIG. 6 shows another embodiment of the movable portion. Each movable portion 2'is not a simple flat plate shape as shown in FIGS. 1 and 3 but has a substantially U-shaped cross section. That is, not only can such a cross-sectional shape reduce friction caused by contact with each other to efficiently and finely move the movable portion independently, but also, for example, alcohol for cleaning when the fiber is automatically fused. It is also possible to exert the function of reducing the surface tension of the liquid film (not shown) that hinders the sliding between the movable parts, which occurs when the liquid is sprayed.

The entire shape is comb-shaped, and the grooves are mounted displaceably in the depth direction of each groove, and each optical fiber is placed in the V groove formed by the inclined surface on the tip side of the fixed portion and the movable portion.

Since the optical fiber is blocked by the section, each optical fiber can perform accurate aligning work independently and simultaneously without interfering with each other's aligning operation, thereby improving reliability and aligning. It is possible to achieve a dramatic improvement in accuracy.
