Mode-bases gain difference for Different phase profiles in Few-mode Erbium-doped Fiber Amplifiers
Advanced Photonics NexusIn few-mode erbium-doped fiber, which is key sections in space division multiplexing (SDM) communication system, linearly polarized (LP) and orbital angular momentum (OAM) mode as two groups of mode-bases with different phase profile can be transformed into each other for the fiber’s weakly guiding condition.

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 ...

We develop a rigorous procedure for the optimum design of few-mode erbium (Er)-doped fiber amplifiers, which is tackled as a multiobjective optimization problem, in an approach based on the combination of the topology optimization and genetic algorithm techniques.

A few-mode erbium-doped fiber (FM-EDF) is fabricated using modified chemical vapor deposition in combination with liquid solution. The core and cladding diameters of the fiber are approximately 19.44 and 124.12 μm, respectively. The refractive index difference is 0.98%, numerical aperture (NA) is 0.17, and normalized cut-off frequency at 1550 nm is 6 ...
