光学相干系统利用接收到的光信号与本地激光器的干涉来实现高信噪比并捕获信号的幅度、相位和偏振，由于数字信号处理器的改进，光学相干系统在过去十年中已经急剧增长。发射器和接收器的光学器件都变得越来越复杂，其部署大大受益于硅光子学提供的集成。今天的相干系统范围从1.2 Tb/s光纤通信收发器到光学相干断层扫描医疗仪器。本文将概述光学相干系统，介绍目前最先进的硅光子器件的运输，并讨论硅光子学在这一领域的发展。
Optical coherent systems, which employ the interference of a received optical signal with a local laser to achieve high signal-to-electrical-noise ratio and capture the magnitude, phase, and polarization of the signal, have grown dramatically in the last decade due to improvements in digital signal processors. The optics of both the transmitter and receiver have grown in complexity, and its deployment has benefitted greatly from the integration offered by silicon photonics. Today's coherent systems range from 1.2-Tb/s fiber-optic communication transceivers to optical coherence tomography medical instruments. This paper will give an overview of optical coherent systems, present the state-of-the-art in silicon photonic components shipping today, and discuss where silicon photonics is going in this field.
