Few-Mode Erbium-Doped Fiber with Three-Layer Center-Recessed Doping for Gain Equalization
We propose a design method for few-mode erbium-doped fiber (FM-EDF) incorporating stratified doping. In the simulation design, the FM-EDF effectively reduces the differential mode gain (DMG) through the utilization of stratified doping. Simulations indicate that at an input signal power of −30 dBm,...
