Improved Optical Amplification Efficiency by Using Turbo Cladding Pumping Scheme for Multicore Fiber Optical Networks

We realize a multicore erbium-doped fiber amplifier (MCEDFA)with 2 dB optical gain improvement (average) by recycling the residual 0.98 μm pump light from the MC-EDF output. Eight-channel per core wavelength division multiplexed (WDM) Nyquist PM-16QAM optical signal amplification is demonstrated over a 40-minute period. Furthermore, we demonstrate the proposed MC-EDFA’s stability by using it to amplify a Nyquist PM-16QAM signal and evaluating the resulting Q-factor variation. We found that our scheme contributes to reducing the total power consumption of MC-EDFAs in spatial division multiplexing (SDM)/WDM networks by up to 33.5%. key words: multicore-EDFA, cladding pumping, recycle, power consumption
