Abstract

A method for producing a bare fiber taper at a metallized fiber is disclosed and comprises the steps of softening and drawing in an arc of the fiber metallized by sputtering or vapor deposition. The softened metallized fiber thereby constricts and the metallized fiber becomes free of the metallization and, thus, bare over its entire circumference in the arising constriction as a consequence of the influence of the arc. The bare constriction produced in such fashion is parted and a tapering, bare end section thereby arising at one of the two metallized fiber halves produced by the parting can be employed as the bare fiber taper. A fiber taper with lens can be produced by fusing a lens to the bare end section.
