在Cadence环境下建立了一个用于CMOS和光子系统级混合模拟的硅基结行波马赫-曾德尔调制器（MZM）的Verilog-A模型。关键器件功能，如折射率的电压依赖性变化，小信号RLGC参数的MZM臂提取的光子器件表征从OpSIS代工厂。模型中还考虑了热光系数。包括电光S21的仿真结果表征了相位调制器的带宽。此外，瞬态MZM操作与非归零（NRZ）数据传输在10 Gb/s和20 Gb/s的速率进行了演示。
A compact Verilog-A model of silicon-based junction traveling-waveMach-Zehnder modulator (MZM) is developed for hybrid CMOS and photonic system-level simulation in Cadence environment. Critical device functions such as the voltage dependent change of refractive index, small-signal RLGC parameters for the MZM arms are extracted from the photonic device characterization from OpSIS foundry. Thermo-optical coefficient is also considered in the model. Simulation results including electro-optic S21 is characterized for the phase modulator's bandwidth. Also, transient MZM operation with non-return to zero (NRZ) data transmission at 10 Gb/s and 20 Gb/s rates are demonstrated.
