Boron Doped Photosensitive Fiber

      Fibercore’sphotosenstive (PS) series of fibers are co-doped with Boron and Germanium. Thecombination of Boron and Germanium gives extremely high photosensitivity whilstmaintaining a relatively large Mode Field Diameter (MFD). The highphotosensitivity level ensures that high reflectivity Fiber Bragg Gratings(FBGs) can be inscribed in a short period of time with or without Hydrogenloading the fiber. PS-fiber may be used ‘straight from the shelf’, withouthydrogenation, delivering a strong and consistent degree of photosensitivityindefinitely.
      PS fibers provide significant advantages forhigh volume FBG production lines by dramatically reducing the production timeper FBG, for example in diode laser FBG stabilizers and gain flatteningfilters.
      PS1250/1500 has been designed to match the MFDcharacteristics of typical, dual-wavelength, 1310nm and 1550nmtelecommunications fiber, making it ideal for the fabrication of add-dropmultiplexers or Erbium Doped Fiber Amplifier (EDFA) Gain-Flattening Filters(GFFs).
      PS980 has been designed to be used to pigtail980nm EDFA pump diodes, enabling a wavelength-stabilizing (or ‘pump-locking’)grating to be written directly into the pigtail.
