Experimental study and analysis of hydrostatic pressure sensitivity of polymer fibre bragg gratings

Journal Article


Abstract


  • The intrinsic hydrostatic pressure sensitivity of

    polymer optical fibre Bragg grating (POFBG) with different

    diameters are investigated. POFBGs are inscribed in singlemode

    polymer fibre and etched down to different diameters. We

    have experimentally demonstrated that the material properties

    of the polymer optical fibre can change after etching and thus

    the etching procedure can have an impact on the pressure

    sensitivity of the POFBG. It is observed from the experimental

    results that hydrostatic pressure induce a positive wavelength

    shift to the POFBG and the pressure sensitivity of the POFBG

    shows significant increase as the fibre diameter reduces through

    etching. A pressure sensitivity of 0.20 pm/kPa is obtained for

    an un-etched POFBG while for an etched POFBG with 55 µm

    diameter a sensitivity of 0.75 pm/kPa is observed. Temperature

    compensation techniques are also successfully implemented to

    extract the true intrinsic pressure sensitivity of the POFBG.

    Through this study, the intrinsic pressure sensitivity of POFBG

    with different diameters are obtained and also the significance

    of etching and its impact on pressure sensitivity is demonstrated.

    This information can lead to further research and development on

    high sensitivity pressure transducers based on etched POFBGs
