摘要：
A multi-orbital angular momentum (M-OAM) erbium-doped fiber amplifier (EDFA) was theoretically investigated. A five-ring-core structure doped with erbium is introduced, designed to offer relatively flat gain throughout the entire C-band and support up to 150 OAM modes, with each ring capable of supporting a set of 30 OAM modes. Numerical simulations suggest that the proposed M-OAM-EDFA can obtain a highly stable gain exceeding 23.8 dB, maintain a differential modal gain (DMG) less than 1.19 dB, and suppress inter-core crosstalk to a low level of below -165.98 dB. This M-OAM amplifier is promise to a new gateway for the development of 6G and greatly improve the spectral efficiency of the network.
