Method for the controlled modification of the geometric characteristics of the end of an optical monomode fibre, and the use in optical coupling

摘要

the method of the invention is to attack (the end (e1) of a single-mode optical fibre (1) so as to modify the geometrical characteristics.to raise the profile of the far field, and to compare with another optical element (2) coupling mode, such as a semiconductor laser.;by this method, we can increase the efficiency of the coupling between the two elements and / or set a predetermined distance (d) between the two components.
