Fiber Residual Stress Effects on Modal Gain Equalization of Few-Mode Fiber Amplifier [PDF]
Sensors, 2023 The modal gain equalization (MGE) of few-mode fiber amplifiers (FMFAs) ensures the stability of signal transmission. MGE mainly relies on the multi-step refractive index (RI) and doping profile of few-mode erbium-doped fibers (FM-EDFs).
