摘要： The present invention relates in general to coupling of light from one or more input waveguides to an output waveguide or output section of a waveguide having other physical dimensions and/or optical properties than the input waveguide or waveguides. The invention relates to an optical component in the form of a photonic crystal fiber for coupling light from one component/system with a given numerical aperture to another component/system with another numerical aperture. The invention further relates to methods of producing the optical component, and articles comprising the optical component, and to the use of the optical component. The invention further relates to an optical component comprising a bundle of input fibers that are tapered and fused together to form an input coupler e.g. for coupling light from several light sources into a single waveguide. The invention still further relates to the control of the spatial extension of a guided mode (e.g. a mode-field diameter) of an optical beam in an optical fiber. The invention relates to a tapered longitudinally extending optical waveguide having a relatively larger cross section that over a certain longitudinal distance is tapered down to a relatively smaller cross section wherein the spatial extent of the guided mode is substantially constant or expanding from the relatively larger to the relatively smaller waveguide cross section. The invention may e.g. be useful in applications such as fiber lasers or amplifiers, where light must be coupled efficiently from pump sources to a double clad fiber.

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.
