Definitions
- the present invention relates to an optical fiber array.
- an optical fiber array in which a bonding surface is devised when bonding a substrate and a cover plate to increase the bonding strength.
- an optical fiber array described in Japanese Patent Application Laid-Open No. 2001-343547 has a roughened surface between a housing groove for housing an optical fiber formed on a substrate and an end of the substrate, and is bonded. The area is increased to increase the adhesiveness and prevent the transmission characteristics of optical signals from deteriorating. Disclosure of the invention
- the present invention has been made in view of such problems, and has as its object to provide an optical fiber array that can maintain good transmission characteristics.
- the bonding groove is formed at a depth of 5% to 200% of the depth of the accommodation groove. If the depth of the adhesive groove is less than 5% of the depth of the receiving groove, it will be difficult to regulate the movement of the adhesive layer. If the depth of the adhesive groove is deeper than 200% of the depth of the receiving groove, the adhesive layer will Filling may be difficult and the adhesiveness may be reduced.
- FIG. 7 is a table summarizing the measurement results of the examples and the comparative examples.
- the bonding groove 36 is a groove formed between the opening edge of the outermost housing groove 34a and the end of the substrate 30 and into which the bonding layer 16 enters.
- the shape of the adhesive groove 36 is not particularly limited as long as the adhesive layer 16 can penetrate to increase the adhesive area and regulate the expansion and contraction movement of the adhesive layer 16. Is formed.
- the angle 02 between the forming surface of the bonding groove 36 formed in a V-shaped cross section and the forming surface (see FIG. 2) is 55 ° to 95 °.
- the angle is preferably from 65 ° to 85 °, and more preferably from 60 ° to 80 °.
- the bonding layer 16 enters the bonding groove 36 formed between the housing groove 34a and the end of the substrate 30. Therefore, the bonding area between the substrate 30 and the lid plate 12 increases. In addition, the curing shrinkage of the adhesive and the expansion and contraction due to heat may occur in the adhesive layer 16. However, since the substrate 30 has higher rigidity than the adhesive layer 16, the adhesive layer 16 has an adhesive groove. The movement of the adhesive layer 16 caused by the penetration and contraction of the adhesive layer 36 penetrating into 36 is regulated by the surface on which the adhesive groove 36 is formed.
- FIG. 5 is a table summarizing the numerical values of the occupancy ratio GZW, the bonding groove depth, the bonding groove angle, the housing groove depth, and the housing groove angle of the optical fiber array 10 of the first embodiment.
- the table of FIG. 8 and Comparative Examples 1 to 3 are also shown together.
- the depth of the bonding groove 36 exceeded 200% of the depth of the accommodation groove 34, it was difficult to fill the bonding groove 36 with the adhesive, and the adhesiveness was reduced.
- the depth of the bonding groove 36 was in the range of 5% to 200% with respect to the depth of the housing groove 34. At times, it was found that good transmission characteristics could be maintained.
