ABSTRACT:
An optical fiber fixing element consists of a glass tube having an inner hole for receiving a clad portion of an optical fiber and which is formed at one end with a conical flared portion converging into the inner hole and a recess for receiving a cover portion of the optical fiber thereinto, both the flared portion and the recess being formed concentrically with the glass tube. A method of manufacturing such optical fiber fixing element is also provided which comprises forming an erosion resistant film on an outer surface, other than an end face, of a glass tube having an inner hole, treating the end face of the glass tube with a glass erosive solution to thereby form a flared portion, and grinding the flared portion to thereby form a recess in the flared portion.
