Patent ID: 7606454

Claim:
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.
