Abstract

It is shown that for practical pump powers ( 33dB) and low noise figure (3dB) cannot simultaneously be achieved with a conventional co-directionally-pumped EDFA. However, using a composite EDFA incorporating an isolator overcomes the problem and we demonstrate an amplifier with 51dB (54dB) gain and 3.1dB NF for only 45mW (93mW) of pump power.
