Abstract

An optical fiber array includes a plurality of single-core fibers each having a core and a cladding and each having, in a distal end surface thereof, a beam expanding portion capable of expanding a mode field diameter (MFD) of light propagating in the core, and a ferrule having an optical fiber holding hole into which the plurality of single-core fibers are inserted, and an end surface in which the optical fiber holding hole opens. A cladding diameter of each of single-core fiber in the beam expanding portion decreases toward the distal end surface. The optical fiber holding hole has a tapered portion whose inner diameter decreases toward the end surface and against which the distal end surfaces abut.
