Ring-Core Multicore Few-Mode Erbium-Doped Fiber Amplifier

IEEE Photonics Technology Letters, 2017
In this letter, we demonstrate a seven-core few-mode erbium-doped fiber amplifier by core pumping for long-haul transmission system using a few-mode multicore fiber. The differential modal gain between the LP01 and LP11 modes is reduced to 3.2 dB or less regardless of the pumping-light mode using a ring-core refractive-index profile, and flattened ...

Few-mode fiber transmission with in-line few-mode erbium-doped fiber amplifier

SPIE Proceedings, 2013
We 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 ...

Few-mode Erbium Doped Fiber Amplifiers

2013 18th OptoElectronics and Communications Conference held jointly with 2013 International Conference on Photonics in Switching, 2013
We review recent work on fiber amplifiers for optical communication systems relying on mode-division multiplexing. This work includes results from a record 6-mode few-mode erbium doped amplifier demonstration.

All-fiber few-mode erbium-doped fiber amplifier supporting six spatial modes

Chinese Optics Letters, 2019
Using the few-mode erbium-doped fiber (FM-EDF) with a simple two-layer erbium-doped structure, we demonstrate an all-fiber FM-EDF amplifier. The gain equalization among the six spatial modes supported by the FM-EDF is achieved when only the pump in the fundamental mode (LP01) is applied.
