Abstract

We introduce a semiconductor optical amplifier (SOA) chip with high gain (>40 dB) and high saturation power (>21 dBm) with moderate drive current (1.3A). A design model for optimizing the new dual-section SOA concept is presented. The model predictions are in very good agreement with the measurement results on fabricated chips. Using the gain and saturation output power product as the figure of merit, it shows the best-reported trade-off result so far. However, due to the slight degradation of the noise figure that ensued, an advanced design is introduced, enabling the optimization of the noise figure in addition to the gain and saturation output power.

具有大增益、小噪声系数和高饱和输出功率级的新型 SOA 设计

我们介绍了一种具有高增益（>40 dB）和高饱和功率（>21 dBm）且驱动电流适中（1.3 A）的半导体光放大器（SOA）芯片。本文提出了一个用于优化新型双截面 SOA 概念的设计模型。模型预测结果与制造芯片的测量结果非常吻合。使用增益和饱和输出功率乘积作为优越性指标，它显示了迄今为止报告的最佳权衡结果。不过，由于随之而来的噪声系数略有下降，因此引入了一种先进的设计，除了增益和饱和输出功率外，还能优化噪声系数。

期刊介绍： The IEEE Journal of Quantum Electronics is dedicated to the publication of manuscripts reporting novel experimental or theoretical results in the broad field of the science and technology of quantum electronics. The Journal comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems and applications must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum-electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics.
