硅光子学的研究可以追溯到20世纪80年代。然而，过去十年见证了该领域的爆炸性增长。硅光子学是一种颠覆性技术，有望彻底改变许多应用领域，例如数据中心，高性能计算和传感。硅光子学背后的关键驱动力是使用CMOS类制造的能力，从而以低成本实现大批量生产。这是将光子学引入一系列技术领域的关键使能因素，在这些技术领域中，使用传统光子元件（诸如用于电信行业的那些）的实施成本将是过高的。然而，硅作为光子材料确实具有许多缺点。在其基本形式中，它不是制造例如光源、光调制器或光电探测器的理想材料。近年来，学术界和工业界的大量研究工作推动了对这些问题和其他问题的多种解决方案的论证，随着时间的推移，越来越多的新方法正在被构思出来。很明显，硅光子学有着光明的未来。然而，随着越来越多的方法可用，未来的硅光子集成电路会是什么样子？这份硅光子学路线图深入研究了该领域的不同技术和应用领域，深入了解了全球研究人员面临的最新技术以及当前和未来的挑战。来自工业界和学术界的专家撰写的论文提供了硅波导平台、光源、光调制器、光电探测器、集成方法、封装、硅光子学应用以及满足中红外波长应用所需方法的概述和展望。在科学和技术的进步，以满足在这些领域所面临的挑战，每个领域也解决了一起预测该领域注定要达到。
Silicon photonics research can be dated back to the 1980s. However, the previous decade has witnessed an explosive growth in the field. Silicon photonics is a disruptive technology that is poised to revolutionize a number of application areas, for example, data centers, high-performance computing and sensing. The key driving force behind silicon photonics is the ability to use CMOS-like fabrication resulting in high-volume production at low cost. This is a key enabling factor for bringing photonics to a range of technology areas where the costs of implementation using traditional photonic elements such as those used for the telecommunications industry would be prohibitive. Silicon does however have a number of shortcomings as a photonic material. In its basic form it is not an ideal material in which to produce light sources, optical modulators or photodetectors for example. A wealth of research effort from both academia and industry in recent years has fueled the demonstration of multiple solutions to these and other problems, and as time progresses new approaches are increasingly being conceived. It is clear that silicon photonics has a bright future. However, with a growing number of approaches available, what will the silicon photonic integrated circuit of the future look like? This roadmap on silicon photonics delves into the different technology and application areas of the field giving an insight into the state-of-the-art as well as current and future challenges faced by researchers worldwide. Contributions authored by experts from both industry and academia provide an overview and outlook for the silicon waveguide platform, optical sources, optical modulators, photodetectors, integration approaches, packaging, applications of silicon photonics and approaches required to satisfy applications at mid-infrared wavelengths. Advances in science and technology required to meet challenges faced by the field in each of these areas are also addressed together with predictions of where the field is destined to reach.
