Abstract

We report an O-band BDFA gain and NF performance over the temperature-range of -40 to +60^oC. A 34dB gain with 5.5dB NF was obtained at 1340nm in a double-pass-BDFA operating at -40^oC. The temperature-dependent-gain was decreased by <0.1dB/^oC for temperatures above -20^oC across 1310-1360nm wavelength-band.
