<p>The invention relates to an optical fiber combiner and a method for the manufacture thereof. The combiner comprises a tapering support preform comprising a plurality of capillary bores, a plurality of input fibers comprising a core and a cladding around the core and being arranged in parallel in the capillary bores of a support preform, and an output fiber coupled to the tapered end of the support preform in optical connection with the input fibers. According to the invention, the cladding thickness to core thickness ratio of at least one of the input fibers is decreased at the region of the support preform. The invention provides an optically high quality fiber combiner.</p> |
