    摘要： The invention relates to an article comprising a length of an optical fiber and a package, the optical fiber comprising a fiber Bragg grating dispersed over a FBG-section of the length of the optical fiber, the package comprising a carrier with a carrier surface for supporting at least a supported part of the optical fiber including the FBG-section. The invention further relates to an apparatus comprising the article, to its use and to a method of manufacturing such an article. The object of the present invention is to seek to provide an optimized (e.g. elongate) package having a relatively low sensitivity to mechanical vibrations from the environment. This is achieved by providing that the carrier surface for supporting the optical fiber comprising a fiber Bragg grating is convex in a longitudinal direction of the optical fiber during use of the article. This has the advantage of providing a lowering of the influence of vibrations from acoustic sources (or other sources of mechanical vibration) in the environment compared to prior art solutions. In an embodiment, the carrier comprises two different materials, each adapted to provide a specific tuning of the wavelength selected by the fiber Bragg grating. The invention may e.g. be used for the fiber lasers for sensing, (low frequency/low phase noise fiber lasers) in wavelength tuneable fiber lasers, and in packaging of fiber lasers in general.
