“…A compatible amplification solution for MDM transmission in FMF is few-mode EDFA (FM-EDFA). The previous study on FM-EDFA focused on high-power laser/amplifiers [137] in which only the fundamental mode is amplified and high-order modes are suppressed. For an FM-EDFA used in MDM, signals contained in all modes must be amplified simultaneously.…”

Space-division multiplexing (SDM) uses multiplicity of space channels to increase capacity for optical communication. It is applicable for optical communication in both free space and guided waves. This paper focuses on SDM for fiber-optic communication using few-mode fibers or multimode fibers, in particular on the critical challenge of mode crosstalk. Multiple-input-multipleoutput (MIMO) equalization methods developed for wireless communication can be applied as an electronic method to equalize mode crosstalk. Optical approaches, including differential modal group delay management, strong mode coupling, and multicore fibers, are necessary to bring the computational complexity for MIMO mode crosstalk equalization to practical levels. Progress in passive devices, such as (de)multiplexers, and active devices, such as amplifiers and switches, which are considered straightforward challenges in comparison with mode crosstalk, are reviewed. Finally, we present the prospects for SDM in optical transmission and networking.

“…EDFA is especially used for discrete amplification in single mode WDM system and is performing well in SDM–WDM system 26–28 . EDFA is used both for single mode amplification and multimode amplification 29–31 . In these literatures, the importance of EDFA in WDM transmission systems was discussed.…”

Summary Space division multiplexing (SDM) is an endowment technology to increase the collective bandwidth of multimode transmission in wavelength division multiplexing (WDM) system. In this paper, four wavelength signals from 229.6 to 232.6 THz are transmitted. For each wavelength, three linearly polarized (LP) modes are multiplexed using SDM. These 12 LP modes are transmitted through four parallel Multimode Step Index (MSI) fibers and received by four optical network units (ONUs). A multimode erbium doped fiber amplifier (MMEDFA) with elevated refractive index profile (ERIP) is used as preamplifier to this SDM–WDM system. This ERIP is complying with ITU‐T G.651.1 standard fiber in dispersion performance. The pumping power of 10 mW is adequate for this MMEDFA which is very low and cost effective. LP modes are transmitted, and performance of proposed transmission system is evaluated in terms of spatial electric fields, pumping power requirement, output optical power, and bit error rate (BER).

“…The theory of multimode EDFAs (MM-EDFA) has been studied in [11]. Applications for MM-EDFAs have included high-powered lasers and free-space communications, where the multimode optical waveguide is essentially used in a "single-mode" manner, thus mode-dependent gain (MDG) is not critical [11,12]. In MDM transmission however, careful control over MDG is necessary to overcome mode-dependent loss (MDL) in the transmission fiber, and to ensure all signal modes are launched with optimal power maximizing the total system capacity.…”

We propose a method for controlling modal gain in a multimode Erbium-doped fiber amplifier (MM-EDFA) by tuning the mode content of a multimode pump. By adjusting the powers and orientation of input pump modes, modal dependent gain can be tuned over a large dynamic range. Performance impacts due to excitation of undesired pump modes, mode coupling and macro-bending loss within the erbium-doped fiber are also investigated. The MM-EDFA may potentially be a key element for long haul mode-division multiplexed transmission.
