| contents | 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. |
