Abstract :
In this paper, for the first time to our knowledge, we have performed EDFA gain spectrum flattening effectively based on a long period fiber grating (LPG), which has been fabricated by the moving fiber/phase mask-scanning beam technique. The results show the flat bandwidth of the related EDFA exceeding 30 nm and the fluctuation is less than 0.6 dB.
