INFLUENCE OF FABRICATION TECHNOLOGY ON METROLOGICAL PROPERTIES OF LONG PERIOD FIBER GRATINGS FOR PRESSURE MEASUREMENTS

Mateusz Smietana, Wojtek J. Bock
  • Abstract:
    The paper presents for the first time a comparative study of long-period gratings (LPGs) written by UV irradiation and by electrical arc discharges and applied to hydrostatic pressure measurements. These gratings were inscribed in a highly photosensitive boron co-doped fiber that can be considered as a suitable platform for LPG writing using either technology. The experimental transmission data for the manufactured LPG devices fit well when compared to the simulations we carried out in parallel. As a result of each of these writing processes, we were able to obtain a remarkably good quality of gratings with highest sensitivities to pressure ever reported, but with the sensitivity depending clearly on the limits of each fabrication technology.
