摘要： In at least some embodiments, an optical module package includes a housing, a plurality of optical fiber cables connected to the housing, and optical fiber connectors terminating each cable. Each optical fiber cable may include an optical fiber, two concentric flexible protective tubes enclosing the fiber, and aramid (e.g. Kevlar®) fibers disposed between the protective tubes. Each protective tube is capable of longitudinally sliding relative to the optical fiber along at least part of the cable, to release stresses resulting from differential thermal expansion of the optical fiber and the protective tubes. Each optical fiber may be held fixed relative to the housing and distal connectors, and one or both of the ends of the protective tubes may be free to move. The protective tubes may also be held fixed relative to the housing, and the optical fiber(s) allowed to move within the housing.

摘要： A method of fabricating multiple superimposed Bragg gratings in the core of a portion of a photosensitive fiber is provided where only one common phase-mask is used. The multiple superimposed Bragg gratings are inscribed in the portion of the photosensitive fiber by applying different predetermined longitudinal stresses to the portion for each corresponding writing. The different predetermined longitudinal stresses are applied to the portion of the photosensitive fiber by stretching the portion along its longitudinal axis bi-directionally and simultaneously such that the centers of all fiber Bragg gratings imprinted in the portion are substantially superimposed at the center of the portion of the photosensitive fiber. The wavelength interval of two superimposed fiber Bragg gratings can be finely tuned to a required value and the wavelength intervals of three or more superimposed fiber Bragg gratings can be optimally tuned to a required wavelength grid, either even or uneven, by changing the effective refractive index of a portion of a photosensitive fiber covering the multiple fiber Bragg gratings inscribed.
