Optical coupling member and optical connector using the same, and optical coupling member holding member

摘要

It is an object of the present invention to simply position a lens and an optical fiber while suppressing an increase in cost. An optical coupling member includes an optical fiber (13), a holder (11) that holds the optical fiber (13) inserted from an insertion hole (11a) formed at one end, and a lens such as a collimator lens (12) accommodated in an accommodation section (11c) formed at the other end of the holder (11), in which positioning is performed by causing the lens and/or the end face of the optical fiber (13) to come into contact with a tapered surface provided at a position facing the lens (12) and the optical fiber (13) in a protruding portion (11e) formed on an inner surface in the vicinity of the accommodation section (11c) of the holder (11).

主权项

1. An optical coupling member comprising:
an optical fiber having an end face; a holding member having a protruding portion and a holding portion that holds the optical fiber inserted at an insertion hole formed at one end of the holding member; and a lens accommodated in an accommodation section formed at the other end of the holding member, wherein the protruding portion is formed on an inner surface of the holding member in the vicinity of the accommodation section thereof, the protruding portion and the holding portion constituting a single component, wherein the protruding portion includes a first tapered surface provided at a position facing the lens, and a second tapered surface provided on the opposite side of the protruding portion with respect to the first tapered surface and disposed at a position facing the optical fiber, and wherein the optical fiber and the lens are arranged so that positioning of at least the optical fiber is carried out by bringing the end face of the optical fiber into contact with the second tapered surface of the protruding portion.
