Our society is on the cusp of a new revolution in integrated circuit technology and manufacturing. The new technology will successfully combine electronic and photonic systems creating previously unimagined functionality and performance. Such sophisticated electronic-photonic systems-on-chip with highly-efficient use of area, energy and spectral resources are critically needed in many communication scenarios. For example, current data-centers and high-performance supercomputers are both power-constrained. High-bandwidth density and high-energy efficiency photonic interconnects would allow the connectivity down to the processor chip level increasing the power-efficiency and utilization of the whole data-center, significantly impacting the national energy consumption in the next decade. However, the lack of large-scale integration approach, design methodology and unified cross-layer design has prevented the realization of these systems. The impact of the electronic-photonic designs and system design methodology proposed in this project spans not only communication systems, but also a variety of other sophisticated electronic-photonic systems (e.g. detection, sensing, and instrumentation). The multi-disciplinary work will educate a unique crop of engineers and scientists that cross the boundaries of electronic and photonic systems. The objective of the research project is to utilize recently developed large-scale electronic-photonic integration approaches to design short-reach coherent-modulation photonic links that significantly improve the area, energy and spectral-efficiency. The proposed electronic-photonic circuit topologies for coherent high-order modulation transmitters and receivers leverage the advantages of each domain and correct for the non-idealities in the other. Starting from the modeling and simulation infrastructure, the proposed research comprises a unique simulation and modeling framework in Verilog-A, which allows for true co-simulation of photonic and electronic circuits, under large signal, non-linear, time-varying conditions. This capability gives vital insights into the interaction of electronic and photonic circuits. It is essential for the use of the resonant components as the second key ingredient in designing efficient electronic-photonic communication systems. Although energy and area efficient, the resonant components require sophisticated wavelength stabilization loops and electronic drive to compensate for their transfer-function characteristics, which are enabled by the co-simulation methodology and abundance of high-performance transistors in the proposed integration approaches.

我们的社会正处于综合电路技术和制造业的新革命中。这项新技术将成功结合电子和光子系统，从而创造出先前想象的功能和性能。在许多通信方案中，需要高效地利用面积，能源和光谱资源的芯片上的复杂的电子光系统系统。例如，当前的数据中心和高性能超级计算机都是功率约束的。高带宽密度和高能效率光子互连将使连通性降低到处理器芯片水平，从而提高了整个数据中心的功率效率和利用率，从而显着影响未来十年的国家能源消耗。但是，缺乏大规模集成方法，设计方法和统一的跨层设计阻止了这些系统的实现。该项目中提出的电子光设计和系统设计方法的影响不仅涵盖通信系统，还涵盖了其他各种其他复杂的电子光系统（例如检测，传感和仪器）。多学科的工作将教育跨越电子和光子系统边界的独特工程师和科学家。 研究项目的目的是利用最近开发的大规模电子光电整合方法来设计简短的相干调节光子链接，从而显着改善了该面积，能量和光谱效率。 针对连贯的高阶调制发射器和接收器的拟议的电子光电路拓扑利用了每个域的优势，并纠正了另一个域的非理想性。从建模和仿真基础架构开始，提出的研究包括Verilog-A中的独特仿真和建模框架，在大型信号（非线性，时间变化的条件下），可以真正对光子和电子电路进行真正的共同模拟。该能力为电子和光子电路的相互作用提供了重要的见解。在设计有效的电子光通信系统时，将共振组件用作谐振组件作为第二个关键要素至关重要。尽管能量和面积有效，但谐振组件需要复杂的波长稳定回路和电子驱动器来补偿其传递功能特征，这是通过拟议集成方法中的共模拟方法和高性能晶体管的丰度来实现的。
