我们提出了一种计算微系统，它独特地利用了硅光子互连的带宽，密度和延迟优势，以实现高度紧凑的超级计算机规模的系统。我们描述和证明单节点和多节点系统与波长路由的光链路互连，量化他们的好处相对于A-维斯于电连接的系统，分析组成的光学组件和系统的要求，并提供一个概述的关键技术需要实现这一系统的愿景。这一愿景要求将能量减少一百倍以上，以传递光学信息。我们探讨了光子链路的功耗，提出了一个路线图，以降低每比特的能量的硅光子互连，并确定了挑战，将面临的设备和电路设计人员实现这一目标。
We present a computing microsystem that uniquely leverages the bandwidth, density, and latency advantages of silicon photonic interconnect to enable highly compact supercomputer-scale systems. We describe and justify single-node and multinode systems interconnected with wavelength-routed optical links, quantify their benefits vis-A-vis electrically connected systems, analyze the constituent optical component and system requirements, and provide an overview of the critical technologies needed to fulfill this system vision. This vision calls for more than a hundredfold reduction in energy to communicate an optical bit of information. We explore the power dissipation of a photonic link, suggest a roadmap to lower the energy-per-bit of silicon photonic interconnects, and identify the challenges that will be faced by device and circuit designers towards this goal.
