Abstract

We fabricated the multi-core erbium-doped fibers (MC-EDFs) and successfully designed a core-pumped four-core erbium doped-fiber amplifier (EDFA). By optimizing the injected pump powers of four fiber cores, we experimentally demonstrated the amplification characteristics. Eventually, an average gain of 25.08 dB with a low inter core gain difference of less than 0.72 dB and an average noise figure of 5.42 dB over the whole C-band were obtained. Besides, the performance of this four-core EDFA was tested under different signal input powers, and the gain difference between different fiber cores can be as low as 0.33 dB.
