Title: 高速硅光子收发器设计中使用标准电子电路仿真器的电光协同仿真

Abstract: The increasing demand for high-speed optical interconnects necessitates integrated photonic and electronic solutions. Electro-optic co-simulation is key to meeting these requirements, which works by importing interoperable photonic models into industry-standard electronic circuit simulators from Synopsys, Cadence, Keysight, and others. However, current interoperable photonic models cannot accurately predict performance and do not address terabit-class transceiver designs due to inadequate modeling of complex physical effects such as optical losses, back-reflection, nonlinearity, high-frequency response, noise, and manufacturing variations. Here, we present accurate and interoperable photonic models that agree well with experiments at symbol rates exceeding 50 Gbaud. The developed models include basic optical components with losses and reflections, two types of Mach-Zehnder modulators with validated high-frequency response, and testing equipment with associated noise. We built an optical link testbench on an industry-standard electronic circuit simulator and verified the model accuracy by comparing simulation and experiment up to 64 Gbaud. The results suggest that co-simulation will be a solid basis for advancing design of transceivers and other related applications in silicon photonics. Show Chinese abstract

Abstract: 随着对高速光互连的需求不断增加，需要集成的光子和电子解决方案。电光协同仿真对于满足这些要求至关重要，其方法是将可互操作的光子模型导入来自Synopsys、Cadence、Keysight等公司的行业标准电子电路仿真器中。然而，当前的可互操作光子模型无法准确预测性能，并且由于对复杂物理效应（如光损耗、背向反射、非线性、高频响应、噪声和制造变化）建模不足，未能解决太比特级收发器设计。在此，我们提出了准确且可互操作的光子模型，在符号速率超过50 Gbaud的情况下与实验结果高度一致。所开发的模型包括具有损耗和反射的基本光学元件，两种具有验证过的高频响应的马赫-曾德尔调制器，以及带有相关噪声的测试设备。我们在行业标准电子电路仿真器上构建了一个光链路测试平台，并通过将仿真与实验进行比较，验证了模型的准确性，最高达到64 Gbaud。结果表明，协同仿真将成为推进硅光子学中收发器及其他相关应用设计的坚实基础。
