摘要

Our proposal is to create a design for a three-mode erbium-doped fiber amplifier (3M-EDFA) that is specifically intended for use in a system that combines mode division multiplexing (MDM) and wave division multiplexing (WDM) techniques. After the efficacious completion of concurrent fiber parameters and innovative branching matrix multi-optimization for erbium profile. The 3M-EDFA system, with cladding pump power, demonstrates remarkable performance, achieving a gain surpassing 24.152 dB and a noise figure below 4.462 dB for all 48 channels evenly distributed across the LP01, LP11, and LP21 signal modes. Across all the channels, 3M-EDFA exhibits gain excursion (GE) and noise figure excursion (NFE) of 0.663 dB and 0.428 dB, respectively. Furthermore, it is noteworthy that the pinnacle values attained for the differential modal gain (DMG) and differential modal noise figure (DMNF) within the wavelength range of 1543 nm to 1558 nm are a mere 0.0563 dB and 0.23 dB, respectively. Our proposed FM-EDFA system possesses the desirable characteristics of minimal excursion in both gain and noise, making it an excellent choice for future high-capacity MDM-WDM networks.
