Abstract
To enable surface tension forces to confer upon an optical fiber end (P1), a shape procuring good optical coupling the end is partially melted in an electric arc (ZC). To improve the reproducibility of this shape movement into the arc is achieved by a unidirectional sideways displacement (MC) of the fiber at an angle to the optical fiber axis. The invention applies to coupling a flat array of optical fibers to a strip of components such as semiconductor lasers. To this end the fibers (F1, . . . , F6) are fixed into grooves on a fiber support (2). The latter is displaced to dip the fiber ends simultaneously into a chemical etching bath which gives them a pointed shape and then to move them successively into the electric arc.
