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.

Optical coupling system

A transmission device contains a plurality of laser transmitters that can be driven individually with a driving current and output optical signals and whose operating point is set via a respective bias current. Each bias current has an individual correction current impressed on it. The correction currents are dimensioned such that, for the same bias current, the laser transmitters have an identical or essentially more uniform average optical output power at the desired operating point.
