Abstract

The invention relates to a method and a device for producing at least one microstructure (5) on an axial end (1a) of an optical fiber (1). The method comprises the following steps: —providing (S10) the optical fiber (1); —wetting (S20) the axial end (1a) of the optical fiber (1) with photoresist (2); —orienting (S30) the optical fiber (1) and a writing beam of a 3D printer with respect to one another; —forming (S40) the at least one microstructure (5) by exposing the photoresist (2) to light with the aid of the 3D printer.
