Abstract
A multicore erbium-doped fiber (MC-EDF) amplifier for simultaneous amplification in the 7-cores has been developed, and the gain and noise properties of individual cores are studied. For a pump power of 146 mW, the average gain achieved in the MC-EDF fiber was 30 dB, and noise figure was less than 4 dB. The net useful gain from the multicore-amplifler, after taking into consideration of all the passive losses, was about 23–27 dB. Pump induced ASE noise transfer between the neighboring channel was found to be negligible.
