Abstract

We have studied the effect of radiation-induced degradation (RIGD) and recovery of the output optical power for erbium-doped fiber amplifiers (EDFAs) in a master oscillator power amplifier (MOPA) setup before and after radiation exposure using a 60Co gamma-ray source. Our preliminary results indicate that the fibers that are not optimized have a complete degradation of gain after exposure to a 10 kRad (100 Gy) dose, where all input signal power is absorbed. We present our efforts where we have improved the degradation to values where the fibers have a significant reduction in gain degradation after exposure. Results of our efforts for further improvement will be discussed.
