ABSTRACT:
A coupling arrangement for coupling light of a semiconductor laser diode into a multimode glass fiber. The laser diode emits light along a first optical axis, and the glass fiber receives this light through a light entry surface and transmits it along a second optical axis. The received light forms a maximum intersection angle with the second optical axis which angle is greater than it would be in case both axes coincided. In a preferred embodiment, the laser light is emitted in form of a wedge having a plane of symmetry which bisects the angle of aperture of this wedge and contains the first optical axis. Best results are obtained in this embodiment, if the angle of aperture is about 10.degree. and the maximum intersection angle is up to 8.degree..
