Abstract

We report on the recent development of multicore fiber amplifiers suitable for amplifying space division multiplexed signals. We designed and constructed 7-core amplifiers, where the cores could be pumped individually or simultaneously through the cladding and studied the amplification and noise properties of these amplifiers. In the core-pumped amplifier, the net average gain was 25 dB, and noise figure was less than 4 dB. Using side-coupled cladding pumping, gain over 25 dB was obtained in each of the cores over a 40-nm bandwidth covering the C-band. We present results of numerical simulation that shows ways of further improvement of amplifier performance, including gain, noise figure, and power conversion efficiency (PCE) through optimization of fiber design.
