Description

[Detailed Description of the Invention] [Field of Application of -] This invention arranges the connection surfaces of the tips of a plurality of optical fibers on a collective board, and connects the plurality of optical fibers to the collective board. The present invention relates to a device that selectively connects respective connection surfaces to create an optical fiber type optical device.

[Prior Art] The originator of the present invention, IJI, previously proposed making a new optical fiber branching coupler using optical fibers.

(Refer to Japanese Patent Application No. 63-149296.) This is an optical branching coupler composed of optical fibers, in which a split mirror is provided on a part of the end face of the constituent optical fibers, thereby dividing the optical power into 4j parts in the core cross section. An optical fiber branching coupler characterized in that a part of the optical fiber is spatially divided, reflected and refracted in another direction, and the light is split by inputting the light into a separately provided optical fiber. Since the optical branching coupler is formed by using optical fibers that are in practical use as they are, it can be installed relatively easily at a low cost. Moreover, the shape is extremely small, and the performance as an optical branching coupler is comparable to that of conventional ones.

Further, the present invention will be explained with reference to the first page of the first page.

Is Figure 14 the simplest? FIG. 2 is a side sectional view of a T-shaped branch coupler with an opening space; That is, the optical fiber 31°32
has a connecting surface 34 whose tip axis is cut obliquely, and a branch optical fiber 33 is arranged in a single character shape on the side of this connecting surface 34.
A branch coupler 30 is constructed by connecting the two. Then, a metal coating is partially formed on the surface 34a of the lower side of the cut connection surface 34 on the side of the branched optical fiber 33 using a knob 7'7'' to form a split mirror.

Figure 15 shows the same assembly board written in Figure 14 and the turning T-shape η1.
A branching coupler 30' is shown, and in this case, the tip of the branched optical fiber 33' or h (the root surface becomes the optical fiber 31',
32' and connected to be inserted into the connecting surface 34'. Then, a metal coating is vaporized on the right side of the roof surface at the tip of the branched optical fiber 33'.
It becomes. Therefore, in this example, the propagating light 35' of the optical fiber 31' is split into the transmitted light 36' guided to the optical fiber 32' and the branched optical fiber 33' by the mirror 34a.
The reflected light 37' is reflected by four people.

To form such a branch coupler 30, 30',
As shown in FIG. 16 (A), apply a metal coating A to the length t of the joint surface 34 cut on the body of the tip of the optical fiber 12 to form an IA mirror 34a'. (B
), this can be achieved by forming a metal coating with $R or the like on only one surface of the roof surface at the tip of the optical fiber 33' and connecting it. Also, the deposition of such a metal coating may be performed in the first step.
As shown in 6IA(C), the connecting surfaces of the optical fibers 38 and 39 can be defined and formed by vapor deposition on the V-shaped groove surface on the I- side.

Optical branching and coupling in two examples of the same assembly board above! The optical power propagating through the fiber 31.31' is 35.35
Is there a part that is spatially distributed within the cross section of the fiber core?A part that is reflected by the one-segment mirrors 34a, 34a and a part that is not reflected by the mirrors 34a and 34a. The components of the reflected light proceed westward toward the fibers 32 and 32' (/: l-4-), respectively, so that the reflected light components change their course toward the branched optical fibers 33 and 33'. Propagating 6 As a result, branching of the light is achieved.

This IE is achieved only when the light is supplied from the optical fibers 31, 31', and the light supplied from the optical fibers 32, 32' and 33, 33-.
Even if such a function does not occur, it can be said that such a branching and combining function is directional.

-On the other hand, the combination of optical signals is achieved as follows. Now, the optical fiber is 32.32"l and the optical fiber is 33.33".
'The light supplied from the IJ mirror 34
a, 34, or the remaining portion goes straight and enters the optical fiber 31°31. -・Power, light]
)・Iha 4J1 of the light supplied from 33° 33' is partially reflected by the mirrors 34a and 34a' and enters the optical fiber 31.31'. As a result, these two optical signals are connected to the optical fiber 31°31' after being combined.
It will be sent to There is no such JafE for other incident lines f[. Therefore, this optical coupling has directionality.

In the manufacturing method, a plurality of light sources 31 31
When the connection surfaces of '32.32' are placed in one place and the connection surfaces of the optical fibers at this location are selectively connected, it is necessary to hold and align the connection surfaces of the fibers. It was done by hand.

[Problem to be solved by invention or solution 17] In this way, the optical fibers were connected completely manually in 7Rs, and the optical fibers were extremely fine and L2
Connection surface 34.34 shown in FIGS. 14 and 15
17-, In 1, there is a problem that there is a lot of variation in quality because it has to be precisely matched, and it also takes a lot of work time, which is very poor in manufacturing efficiency.Especially, it is necessary to make a connection work first on the connection surface. These positioning operations are time consuming, and it is difficult to locate these connecting surfaces with +3-accuracy, so only highly skilled technicians can perform these tasks. As a result, the manufacturing cost will increase significantly.
