Analytical method for few-mode erbium doped fiber amplifiers
Laser Physics Letters, 2020Abstract An analytical method for few-mode erbium doped fiber amplifiers (EDFAs) is proposed by introducing the uniformity coefficient of population inversion. The validity of the derivation process of the analytical method is identified by the numerical method.

Few-mode fiber transmission with in-line few-mode erbium-doped fiber amplifier
SPIE Proceedings, 2013We demonstrate wavelength-division multiplexed (WDM) and mode-division multiplexed (MDM) transmission over a fiber recirculating loop comprising of a 25-km span of low differential mode group dispersion (DMGD) few-mode fiber carrying the LP01 and LP11 mode groups, and an inline few-mode erbium-doped fiber amplifier (FM-EDFA) providing low mode ...

Vector Mode effects in Few Moded Erbium Doped Fiber Amplifiers
Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2013, 2013We numerically investigate the effects of vector mode evolution in FM-EDFAs and show that evolution of the transverse pump and signal intensities can have a profound effect on the detailed amplifier performance depending on the nature of the pump and signal modes involved.

Gain equalization for a few-mode erbium-doped fiber amplifier supporting eight spatial modes
Applied Optics, 2023A trench-assisted ring few-mode erbium-doped fiber amplifier (FM-EDFA) supporting eight spatial modes is designed and proposed in this work. The gain equalization for the FM-EDFA is achieved by selecting the appropriate doping radius and concentration using a particle swarm optimization (PSO) algorithm when only the pump in the fundamental mode (LP01 ...

Modal gain equalization in a few moded Erbium-doped fiber amplifier
2012 IEEE Photonics Society Summer Topical Meeting Series, 2012We present results on broadband gain equalisation in a MM-EDFA for SDM transmission obtained by optimization of the pump launch and careful tailoring of both the fiber refractive index profile and erbium ion distribution.
