摘要

我们提出了一个由宽带单行载波光电二极管、光导天线和硅光子集成电路组成的纯差太赫兹光谱系统，用于纯差检测。毫米级硅光子电路大大减少了环境温度波动对探头和参考信号之间相干性的影响，并能够在高达1太赫兹的频率下可靠地测量被测样品的相位信息。

Terahetz homodyne spectroscopy system based silicon photonic integrated circuit

We present a homodyne terahertz spectroscopy system consisting of a broadband uni-travelling carrier photodiode, photoconductive antenna, and silicon photonic integrated circuit for the homodyne detection. Millimeter-scale silicon photonic circuits greatly reduce the impact of the environment temperature fluctuations on coherency between probe and reference signals and enable reliable measurement of the phase information of samples under test at up to 1 THz.
