We have developed a multicore erbium doped fiber (MC-EDF) with an increased absorption coefficient for the batch pumping. We fabricated a cladding-pumped type amplifier using the developed fiber and realized a gain of 18.0 dB, a noise figure (NF) of 6.1 dB and a core to core crosstalk of -44.0 dB in the C-band.
