| 英文摘要 | The invention relates to: An optical coupler for coupling light from at least two input fibres into one output fibre. The invention further relates to a method of fabricating and to the use of an optical coupler. The object of the present invention is to provide an optical coupler, which is relatively easy to manufacture. The problem is solved in that the coupler comprises a) an input section comprising at least two input fibres, which are bundled over a bundling-length and having an output end face at one end of the bundling-length; and b) an output section comprising an output fibre comprising a confining region for confining light propagated in said input fibres and a surrounding cladding region and having an input end face; wherein said output end face of said input section is optically coupled to said input end face of said output section and at least said confining region of said output fibre is tapered down from a first cross sectional area at said input end face to a second, smaller cross sectional area over a tapering-length of said output fibre. This has the advantage that the output section comprises an optical fibre which can be made in easy to handle, appropriate lengths and which can be easily tapered. The invention may e.g. be used in fibre lasers or amplifiers, where efficient coupling of light from a number of pump sources to a single (e.g. double clad) output fibre is needed. |
