Abstract
An arrangement which converts a plurality of light beams having a small beam cross-section into a light beam having a larger cross-section comprises a plurality of waveguide cores with each core having a first end face which is oblong and arranged for receiving light from each of the light rays having the smaller beam cross-section and each core has a second end face which are arranged together and extend in a different direction than the first end faces for coupling light with the beam having the large beam cross-section. Preferably, each of the cores is fashioned in the form of a bisphenoid so that the first and the second core end faces are oblong in directions extending perpendicular to one another.
