Radiation Effects on Fiber Bragg Grating Sensors Written in UV KrF Laser Process Condition Kim, Jong-Yeol; Lee, Nam-Ho; Jung, Hyun-Kyu;
We studied the effect of gamma-radiation on the FBGs by a variation of grating the fabrication parameters. The FBGs were fabricated in a different UV KrF laser intensity using the same boron co-doped photo-sensitive fiber and exposed to gamma-radiation up to a dose of 33.8 kGy. According to the experimental data and analysis results, We confirmed that the laser intensity for grating inscription has a highly effect on the radiation sensitivity of the FBGs and the radiation-induced Bragg wavelength shift by the change of laser process condition showed a difference more than about 30 %.
