Recently, multi-core fibers have performed prominently in the field of space division multiplexing (SDM) due to their multi-channel characteristics. As an important component of the SDM system, multi-core fiber amplifiers face huge challenges compared to single-channel amplifiers in front-end and back-end coupling devices, pumping methods, and amplification performance. Based on this, we propose and develop a 7-core erbium-ytterbium co-doped microstructured fiber amplifier (7CEYDFA) for efficient multi-core fiber amplification. By using air holes to surround the inner cladding, the double cladding structure can effectively isolate the pump light. At the same time, the specially prepared high concentration doped core rare earth material can ensure that 7CEYDFA can achieve efficient amplification within only 90cm. Through experimental tests, 7CEYDFA achieved a gain of 20.9dB at 1532nm.
