In mode-division multiplexing (MDM) optical transmission systems and MDM networks, the gain must be kept nearly constant even when the input signal power of the few-mode (FM), erbium-doped fiber amplifier (EDFA) changes. This paper investigates controllability of the gain in a 4-LP mode EDFA, whose EDF has signal modes of LP

Journal of Computational Electronics, 2021
This paper describes the system performance of mode division multiplexing applications. The mode of amplification involved a ring profile-based multi-mode erbium-doped fiber amplifier with minimum support of 10 vortex spatial modes. The vortex modes are configured and generated by the vortex lens whose input is excited by a spatial laser source.

Latest results and future perspectives on Few-Mode Erbium Doped Fiber Amplifiers
Optical Fiber Technology, 2017Abstract Space division multiplexing has generated a lot of interest during the last five years and motivated intensive work on multicore and few-mode fibers. Whereas some concepts like multimode waveguides and mode coupling have been re-visited for mode-division multiplexing, some new problems have been addressed, as is the case for multimode ...

All-fiber few-mode erbium-doped fiber amplifier supporting six spatial modes
Chinese Optics Letters, 2019Using 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.

Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2013, 2013
We measure the modal gain and noise figure characteristics of a ring-doped few-mode erbium-doped fiber amplifier. We obtained 1 dB higher gain in LP11 than LP01 at an average of 12.5 dB per mode.

We analyze the impact of beating effects between signal modes experimentally by comparing gain values for modulated and CW signals. We measure noticeable differences because of mode beating and mode dependent EDFA saturation.

Few-mode erbium-doped fiber amplifier design method based on the signal-pump overlap integral
Optical Engineering, 2014Space-division multiplexing allows an increase of link capacity by using either multicore or single-core few-mode (FM) optical fibers. In the case of FM systems, each mode carries its own data stream and long-haul transmission can be hampered by the use of conventional erbium-doped fiber amplifiers (EDFAs), since because of distinct field profile ...
