Abstract

Space division multiplexing (SDM) utilizing few-mode fibers or multicore fibers supporting multiple spatial channels, is currently under intense investigation as an efficient approach to overcome the current capacity limitations of high-speed long-haul transmission systems based on single mode optical fibers. In order to realize the potential energy and cost savings offered by SDM systems, the individual spatial channels should be simultaneously amplified with associated SDM amplifiers. In this paper, a review of recent progress on the implementation of various SDM amplifiers for SDM transmission is provided and strategies to minimize the differential modal gain in few-mode erbium doped fiber amplifiers (FM-EDFAs) are presented. In particular, the performance of both core-pumped and cladding-pumped 6-mode EDFAs will be discussed in detail and the prospect of further scaling with respect to the number of spatial modes that can be amplified will be described.
