Problems solved by technology

At this time, since the state of the oxide film changes with the adjustment of the laser intensity, the supply amount of the raw material of the oxide film, and the temperature of the raw material liquid of the oxide film, it is difficult to adjust to a predetermined state and the production efficiency is low.
In addition, it is necessary to use a device for vaporizing the liquid raw material and feeding it into the reaction chamber, which increases the cost due to the cost of the equipment.

Embodiment 1

[0156] Use the flake-shaped adhesive connection member (1) obtained by the above method, such as Figure 33 The optical connection structure is formed as shown. First, use an optical microscope to align the cross-section of the V-groove (with a size of 5 mm × 10 mm) with two alignment members 43a, 43b, and then at a position 0.2 mm away from the 0.05 mm notch 801 provided on the glass substrate 80, The V-shaped end faces are positioned, and the alignment member is fixed on the glass substrate 80 with an adhesive. Then, the sheet-like connecting member 21 is inserted into the cutout of the glass substrate and arranged vertically on the glass substrate. After that, the optical fibers 10a, 10b are arranged in the V-shaped grooves of the both array members 43a, 43b. As the optical fiber, a silica fiber core wire (made by Furukawa Electric, 250μm in diameter, single mode) was used, and the coating was removed approximately 25mm from the end with a fiber stripper, and the bare fiber of ...

Embodiment 2

[0160] Using the sheet-like viscous connection member (2) obtained by the above method, an optical connection structure was formed as in Example 1. As a result of measuring the connection loss of the connected optical fiber, it was 0.4dB or less, showing good optical characteristics. In addition, the above-mentioned optical connecting structure was subjected to a heat resistance test (according to JIS C 0021) in an environment of 125±2°C and a temperature cycle test in the range of -40°C to 75°C. The result was The light loss variation was 0.4dB or less, and the adhesive connection member was observed after the optical connection was disconnected. As a result, no curing or yellowing was observed, indicating that the optical connection member can be fully reused.

Embodiment 3

[0162] Figure 34 It is a plan view showing an optical connection structure for connecting 4-core optical fiber ribbon core wires. In order to realize the optical connection of the four optical fibers to each other, in addition to the use of two 4-core optical fiber ribbon core wires 15a (the optical fibers in this ribbon core wire are 101-104) and 15b, and two V-grooves fixed on the glass substrate 80 Except for the arrangement members 43a and 43b, the connection operation was performed in the same manner as in Example 1, and the four optical fibers were simply optically connected by using a sheet-like viscous connection member 21. In addition, the length of the cleaved optical fiber was detected. As a result, there was a deviation of about ±10 μm between the four bare optical fibers. Since the sheet-like adhesive connecting member can be tightly bonded and fixed to each optical fiber through soft deformation, The variation of light loss between bare optical fibers is also small...

Abstract

There are provided an optical connection structure and an optical connection method capable of holding an optical fiber in a close contact state with a simple structure and easily mounting and detaching the optical fiber while enabling connection having an excellent optical stability. The optical connection structure includes a solid-state adhesive connection member having a refraction factor conformance as a single layer sandwiched between end surfaces of opposing optical transmission media or between the optical transmission media and the optical part. It is preferable that the solid-state adhesive connection member be formed by silicone resin or acryl resin.

Description

Technical field [0001] The invention relates to an optical connection structure for connecting optical transmission media to each other or connecting optical transmission media and optical components, and an optical connection method for forming the optical connection structure. Background technique [0002] As an optical fiber connection method, the optical fiber is connected to each other or a ferrule into which the optical fiber is inserted, and a physical connection method is generally used. Examples of such cases include mechanical connections, optical fiber connectors, etc. Generally, in the case of permanent connection, mechanical connections are used, and in the case of frequent connection and detachment, optical fiber connectors are effective and widely used. Both of these are physically connected by applying squeezing pressure on the end face of the optical fiber in the axial direction. In the case of optical fiber connectors, generally speaking, because the optical fib...
