Method to align optical waveguides at a coupling joint and a coupling element for an optical waveguide switch

摘要

In a method and apparatus for suitably positioning light waveguides for coupling ends of function fibers at coupling locations, the coupling ends of the function fibers are aligned and fixed on a carrier element. Guide capillaries are formed to fit the jackets of the function fibers precisely and are aligned on both sides of a coupling location. The alignment is achieved with the assistance of a wrap-free auxiliary fiber after which the auxiliary fiber is removed and the function fibers are subsequently introduced into the guide capillaries and fixed therein.
