摘要： The invention relates to the field of optical fiber structures, preferably adapted for use with fiber Bragg gratings in sensors. The fiber structure has birefringence and comprises a core and a cladding surrounding the core, a central microstructure (1) comprising a first plurality of longitudinal holes for guiding optical radiation, a side microstructure (2) comprising a second plurality of longitudinal holes, wherein the side microstructure (2) is at least partly surrounding the central microstructure (1) and is adapted for providing a predetermined mechanical anisotropy, a pressure responsive unit, a lateral force responsive unit, a temperature responsive unit, and a birefringence responsive unit adapted for converting birefringence in the core to wavelength information. In this way, a fiber structure is provided that allows increasing the ratio of mechanical to thermal sensitivity up to several orders of magnitude with similar sized mode areas.

摘要： A method is described for designing and/or producing micro-structured fibres (100a, 100b, 100c) having a predetermined polarimetric sensitivity to temperature. The method allows obtaining highly birefringent micro- structured fibres having a limited temperature sensitivity or being temperature independent for specific wavelengths. The latter is obtained by propex-ly selection of the fibre geometry or, if the micro-structured fibre has an arbitrary geometry, by properly choosing the glass used for its manufacturing. The method comprises obtaining information about the geometry and/or about the material to be used. This information then can be used for producing micro-structured fibres. The necessary information about the geometry and/or about the construction material to be used can be obtained based on a model for the temperature sensitivity of birefringent micro-structured fibres. Furthermore, micro- structured fibres having a polarimetric sensitivity to temperature not larger than a predetermined value or even being temperature insensitive for a wide range of temperatures are described.
