Abstract: To ensure laser safety, also in the case of a largest possible coupled optical power, during the direct optical coupling of a light-emitted component to an optical waveguide, an optical system includes coupling the light through a fiber end configured as a multimode step index optical waveguide having a numeric aperture larger than the half-width value of the angular distribution of the radiation emitted from the radiation source. To distribute the radiation fed into the actual optical waveguide over the largest possible angular range with regard to the luminous power, the coupling of the light beam into the fiber end is effected such that the coupled light beams are inclined in relation to the geometric axis of the optical core of the fiber end at a defined angle.

Abstract: The aim of the invention is to ensure so-called laser safety, also in the case of the largest possible coupled optical power, during the direct optical coupling of a light-emitting component (1) to an optical waveguide (20). To this end, the light is coupled via a fiber end (10) which is configured as a multimode step index optical waveguide and whose numeric aperture is larger than the half-width value of the angular distribution of the radiation (2) emitted from the radiation source. In order to distribute the radiation (2'), which is fed into the actual optical waveguide, over the largest possible angular range with regard to the luminous power, the coupling of the light beam into the fiber end is effected in such a manner that the coupled light beams (2') are inclined in relation to the geometric axis of the optical core (11) of the fiber end (10) with a defined angle (f).
