We compare two 6-core annular cladding erbium-doped fibers achieving >19 dB gain and <6 dB noise figure across the C-band. The annular cladding improves the pump power utilization by 40% compared to uniform double-cladding.
We demonstrate two in-line cladding-pumped 6-core Erbium-doped fiber amplifiers with recirculation loop transmission over 465-km coupled-6-core fiber. Total capacity of 7.2-Tb/s SDM/WDM transmission is achieved with a spectral efficiency of 18-bit/s/Hz.
We present designs for a low-loss mode coupler based on multiple Gaussian spots that can selectively address spatial and polarization modes of a few-mode fiber. In particular we show a design optimized for a few-mode fiber with 12 spatial and polarization modes (LP01, the twofold degenerate LP11 and LP21, and LP02), with a mode dependent loss < 1dB and coupler insertion loss < 3dB.
