Abstract
An optical fiber array for insertion-positioning and arranging coated optical fibers in a substrate, in which a plurality of through-holes are formed, wherein a coating of a tip of the coated optical fiber is removed to expose a optical fiber, and wherein with the use of three substrates, the optical fiber of the coated optical fiber is inserted into through-holes of the first and second substrates and is positioned, and the coating of the coated optical fiber is inserted into a through-hole of the third substrate and is positioned.
Claims21
An optical fiber array comprising:
- a plurality of optical fibers each having a coated portion coating said optical fibers and a non-coated portion;
- and
- a first substrate, second substrate, and third substrate that have one or more through-holes for inserting said optical fibers;
- wherein said substrates are arranged in the order of the first substrate, the second substrate, and the third substrate so that the through-holes of the first substrate, the second substrate and the third substrates are opposed to each other;
- wherein said optical fibers are inserted into the one or more through-holes of said opposingly arranged first substrate, second substrate, and third substrate;
- and
- wherein the one or more through-holes of said first and second substrates support the non-coated portion of the optical fibers, and the one or more through-holes of said third substrate support the coated portions of the optical fibers;
- wherein a material of at least said first substrate is silicon, and a silicon oxide film is formed only on a surface of a wall of each of the through holes of at least said first substrate at each of the through-holes thereof.
