摘要

在相干激光雷达系统中，高灵敏度和高功率的光接收机是首选的。在这项工作中，我们展示了顶照apd，它可以同时表现出低过量噪声(k<0.1)和宽3db带宽(14GHz)，在饱和输出(3ma)下具有高响应性(6.7A/W)。

High-Speed and Wide Dynamic Range Avalanche Photodiode for Coherent Lidar Application

A high-sensitivity and a high-power photo-receiver is preferred in coherent lidar system. In this work, we demonstrate top-illuminated APDs, which can simultaneously exhibit low excess noise (k<0.1) and wide 3-dB bandwidth (14GHz) with high responsivity (6.7A/W) under the operation at saturation output (3 mA).
