摘要：

We investigate the temperature dependence of radiation-induced attenuation (RIA) at 1 310 nm for a Ge/P co-doped fiber after a steady-state gamma-ray irradiation. A gamma irradiation facility Co-60 source is used to irradiate the fiber at a dose rate of 0.5 Gy/min, satisfying a total dose of 100 Gy. The test temperature ranges from -40 to 60 degrees C by 20 degrees C, and the RIA of the fiber is obtained using a power measuring device. The experimental result demonstrates that RIA exhibits a steady, monotonic, and remarkable temperature dependence after approximately 48 h of accelerated annealing at 70 degrees C. The optical fiber irradiated with a high dose and annealed sufficiently can be used as a temperature sensor.
