我们报告称,通过结合具有两个反相输出的低 VπMach-Zehnder 调制器、高功率激光器和平衡光电探测器对,无放大器光纤链路的噪声系数达到了创纪录的低噪声系数(在 1.0 – 9.5 GHz 频率范围内≤ 15 dB)。我们还为该链路提供了一个完整的模型,预测其测量性能误差在 1 dB 以内。
We report achieving a record low noise figure for an amplifierless fiber-optic link — ≤ 15 dB over the frequency range 1.0 – 9.5 GHz — via a combination of a low-VπMach-Zehnder modulator with two antiphase outputs, a high-power laser, and a balanced photodetector pair. We also present a complete model for this link that predicts its measured performance to within 1 dB.
