It is known that changes of optical characteristics are caused in optical fibers by irradiation of radiation such as gamma ray. It has been reported that a transmission loss and a modal birefringence change in a polarization-maintaining optical fiber due to irradiation of radiation. In this report, we proposed a method to obtain a modal birefringence change in a polarization-maintaining fiber by measuring the change of reflection spectrum in the polarization-maintaining fiber Bragg grating. The possibility of the method for radiation sensing applications was examined. PANDA fiber Bragg gratings (PANDA-FBGs) were fabricated, and gamma radiations with 1kGy and 10kGy were irradiated to PANDA-FBGs. It was found that both Bragg wavelengths corresponding to two polarization modes shifted to shorter wavelength. It was also confirmed that the modal birefringence in the PANDA fiber decreased by the irradiation of gamma radiation because the difference of Bragg wavelengths decreased after irradiation. |
