Abstract
Long period fiber grating (LPFG) upon all-solid photonic bandgap fiber with a bandgap at 1.068 to 1.180 μm is fabricated by high-frequency CO 2 laser pulse irradiation. The resonance wavelength is 1335.76 nm with a modulation depth of 15 dB and a 3-dB bandwidth of 2.6 nm. Bending response of the LPFG is dependent on the axial orientations and the input polarization states. The maximum bending sensitivity is achieved at 52  nm/m . The temperature response is weakly dependent on the polarization state, and is achieved around 20.47  pmC at a 0-deg polarization azimuth. The bending measurement error resulting from temperature can be negligible within the range of 0.4 to 0.82  m −1 . It is be beneficial to avoiding cross-sensitivity of temperature in bending measurements.
