Abstract
A coupling element for coupling a laser radiation source to a monomode optical transmission fiber. The end of the fiber is monotonically flattened at a temperature at which the fiber core has a viscosity of between 10.sup.7 to 10.sup.8.5 poises. The fiber has a cladding glass chosen to have a viscosity of between 10.sup.10 -10.sup.11 poises at the flattening temperature. This causes the core glass to emerge in the form of a semi-ellipsoidal lens, when the fiber is flattened.
