Few-mode erbium-doped fiber amplifier design method based on the signal-pump overlap integral
Optical Engineering, 2014 Space-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 ...
