“…We have already demonstrated core-pumped multi-element Erbium (Er) doped fiber amplifiers (ME-EDFAs), comprising 3 and 7 Er-doped fiber-elements [22]. Importantly, as shown here, a cladding-pumped Er/Yb-doped 5-element MEF amplifier (ME-EYDFA) has also now been realized [23]. In the cladding-pumped ME-EYDFA, a central fiber-element carries the pump light, which is shared between several surrounding active (signal) fibers, four in the case of the work described here.…”

A novel technological approach to space division multiplexing (SDM) based on the use of multiple individual fibers embedded in a common polymer coating material is presented, which is referred to as Multi-Element Fiber (MEF). The approach ensures ultralow crosstalk between spatial channels and allows for cost-effective ways of realizing multi-spatial channel amplification and signal multiplexing/demultiplexing. Both the fabrication and characterization of a passive 3-element MEF for data transmission, and an active 5-element erbium/ytterbium doped MEF for cladding-pumped optical amplification that uses one of the elements as an integrated pump delivery fiber is reported. Finally, both components were combined to emulate an optical fiber network comprising SDM transmission lines and amplifiers, and illustrate the compatibility of the approach with existing installed single-mode WDM fiber systems.

“…If the fiber-elements are made to touch one another, a cladding-pumped multi-element erbium doped fiber amplifier (ME-EDFA) can be manufactured [11]. This design is similar to the GT-Wave concept used in high power fiber lasers [12].…”

“…1). Since the geometry of the elements is similar to the transmission MEF, ME-EDFAs show no measurable crosstalk between elements [11]. Since a single multimode pump diode is shared among all the elements, this pumping scheme exhibits a cost efficiency that with the absence of any crosstalk between elements, this pumping scheme makes for a cost effective SDM amplifier technology.…”

“…6a) shows the gain and NF performance of individual signal fibers when 6.4W of pump light was launched into the fiber-element P. A maximum gain of 35±2.5 dB was observed per signal fiber element with a minimum NF of 4.7 dB for an input signal of -23dBm. The gain increased to 37±2dB when the launched pump power was increased to 10W 21 . The pump power vs. gain curve is plotted in fig.…”

Abstract.A novel approach of using multi-element fiber (MEF) technology in space-division multiplexing (SDM) systems is presented. This paper reviews the progress in fabrication and characterization of MEF based both ultralow crosstalk transmission and amplifier fibers. Passive 3-element MEFs have been successfully demonstrated for application in telecommunications. An active 5-element MEF amplifier has also been demonstrated in a novel multiport cladding-pumped configuration, in which a central un-doped multi-mode pump fiber-element is surrounded by four Er/Yb-doped active fiber-elements. MEF is compatible with current WDM systems, and there is no need to develop specialized multiplexing/demultiplexing components. Moreover, it offers a smooth upgrade to SDM systems.
