Abstract
We present a high-core-count 32-core multicore erbium/ytterbium-doped
fiber amplifier (32c-MC-EYDFA) in a cladding pumped configuration. A
side pumping technique is employed for ease of pump coupling in this
monolithic all-fiber amplifier. A minimum gain of >17 dB and an
average noise figure (NF) of 6.5 dB is obtained over all cores in the
wavelength range 1534 nm-1561 nm for −4 dBm input signal power. The
core-to-core variation for both amplifier gain and NF is measured to be
<2 dB. The 32c-MC-EYDFA was then tested in a repeatered multicore
fiber (MCF) loop system and transmission over distances >1850 km was
successfully demonstrated. We also compare the total power consumption
of our MC-EYDFAs with that of 32 conventional single core erbium doped
fiber amplifiers (EDFAs) to illustrate the potential power saving
benefits.
