Abstract

We report a double-pass bismuth-doped germanosilicate fiber amplifier providing 40dB gain and <5dB NF at 1440nm, with a record gain per unit length of ≥1.14dB/m. For -23dBm input signal, the gain-coefficient, in-band OSNR, and temperature-dependent-gain coefficient are 0.458dB/mW, 26.9dB, and -0.014dB/oC, respectively.
