Optical fiber array

Abstract

An optical fiber array includes an upper substrate and a lower substrate in which V-shaped grooves are formed. Optical fibers are inserted and arranged in the V-shaped grooves and are solidified using an adhesive. The upper substrate comprises a fiber presser substrate for pressing the optical fibers in the V-shaped grooves and a covered fiber housing substrate in which covered optical fibers are housed. The lower substrate comprises a V-shaped groove section having V-shaped grooves in which the optical fibers are aligned and arranged, a covered optical fiber support section for supporting the covered optical fibers, and a V-shaped groove step section located between the V-shaped groove section and the covered optical fiber support section. The top surface and/or sides of a non-covered optical-fiber section are opened between the V-shaped groove section or the V-shaped groove step section and the coverage-removed end of the covered optical fibers. The optical fiber array minimizes stress remaining therein after an adhesive is hardened to fix the optical fibers, thereby preventing damage to provide longtime reliability.
