Abstract

A coupling configuration for connecting an optical fiber provided with a coupling end face at one end to an optoelectronic element is described. A coupling element is disposed between the end of the optical fiber and the optoelectronic element in order to reduce back-reflections. The coupling element, which is made of an optically transmissive material, is in physical contact with the coupling end face of the optical fiber, and its side facing the optoelectronic element has a surface region which reduces back-reflections. To simplify and shorten the coupling housing, the coupling element is of lens-like configuration, for example in the form of a ball, and is held directly in the coupling housing.
