我们提出了详细的电气和光学模型的元素，包括一个WDM硅光子链路。电子学假设是基于65 nm CMOS节点和光调制器和解复用器是基于微波谐振器。本研究的目标是通过找到完全覆盖可用光功率预算的正确组合（通道数×每个通道的数据速率）来分析链路的能耗和可扩展性。基于在这项工作中提出的一组经验和分析模型，可以设想0.75 Tbps的最大容量为1.9 pJ/位的能量消耗的点对点链路。对于高达0.35 Tbps的聚合比特率，还预测了子pJ/比特能量消耗。
We present detailed electrical and optical models of the elements that comprise a WDM silicon photonic link. The electronics is assumed to be based on 65 nm CMOS node and the optical modulators and demultiplexers are based on microring resonators. The goal of this study is to analyze the energy consumption and scalability of the link by finding the right combination of (number of channels × data rate per channel) that fully covers the available optical power budget. Based on the set of empirical and analytical models presented in this work, a maximum capacity of 0.75 Tbps can be envisioned for a point-to-point link with an energy consumption of 1.9 pJ/bit. Sub-pJ/bit energy consumption is also predicted for aggregated bitrates up to 0.35 Tbps.
