We present the first in-band diode-pumped TDFAs operating in the 2 µm wavelength region and test their suitability as high performance amplifiers in potential future telecommunication networks. We demonstrate amplification over a 240 nm wide window in the range 1810 - 2050 nm with up to 36 dB gain and noise figure as low as 4.5 dB.
我们展示了首个工作在2μm波长区域的带内二极管泵浦掺铥光纤放大器，并测试了它们在未来潜在电信网络中作为高性能放大器的适用性。我们展示了在1810 - 2050nm范围内240nm宽窗口上的放大，增益高达36dB，噪声系数低至4.5dB。
