Abstract

We report a high-concentration Er-Yb co-doped phospho-alumino-silicate fibre providing 18.4±3.9dB multi-channel gain with 5.8dB average NF from 1570-1616nm. At 1616nm, the gain was 19.3dB at 20oC and 25.3dB at -60oC, with a -0.065dB/oC temperature-dependent-gain coefficient. Also, a 10dB single-channel small-signal gain was obtained at 1625nm.
