OPTICAL COUPLING MEMBER AND OPTICAL CONNECTOR USING THE SAME, AND OPTICAL COUPLING MEMBER HOLDING MEMBER

摘要

An optical coupling member includes an optical fiber (13), a holder (11) that holds the optical fiber 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), the optical coupling member performing positioning by causing at least one of the lens and the end face of the optical fiber (13) to come into contact with an abutting surface (11e1, 11e2) formed in the vicinity of the accommodation section (11c) by providing a recess (11e) on an outer circumference near the accommodation section (11c) of the holder (11), in which a plurality of the recesses (11e) are provided on an identical plane orthogonal to an insertion direction of the optical fiber (13).
