    摘要： The present invention relates to an optical fiber comprising at least a first end with an first end facet, the optical fiber comprising a core region capable of guiding light at a first wavelength λ; and a microstructured cladding region surrounding said core region. The cladding region comprises an inner cladding region and an outer cladding region. The inner cladding region comprises inner cladding features arranged in an inner cladding background material having a refractive index n
    1 , said inner cladding features comprising thermally collapsible holes or voids. The outer cladding region comprising outer cladding features arranged in an outer cladding background material, said outer cladding features comprising solid material with refractive index n
    2 , wherein n
    2 is lower than n
    1 . The invention further relates to methods for splicing such an optical fiber to an optical component and to methods for using such an optical fiber.

    摘要： The invention comprises a photonic crystal fiber (PCF) assembly comprising a PCF and at least one ferrule structure. The PCF has a center axis and comprises a core region and a cladding region and a first fiber end section with a first fiber end. The ferrule structure has a center axis and is mounted to the first fiber end section. The ferrule structure comprises an inner ferrule arrangement and an outer ferrule arrangement surrounding the first fiber end section. The inner ferrule arrangement comprises an inner ferrule front section proximally to the first fiber end and an inner ferrule rear section distally to the first fiber end, and each of the inner ferrule sections have an inner diameter and in at least a length thereof fully surrounds the PCF. The inner ferrule rear section is anchored in an anchor length section to the first fiber end section and the inner ferrule front section supports the first fiber end section proximally to the first fiber end.

    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.
