Compact Modeling and Photoelectric Co-simulation of Hybrid BICMOS-Photonic Segmented-Electrode MZM Transmitter

A segmented Mach-Zehnder Modulators (MZM) driver using 0.13\ \mu\mathrm{m}$ SiGe BICMOS with a simulated differential output swing of 3 Vppd and total power consumption of 0.98W is reported in this paper. A compact modeling of the Segmented-Electrode MZM designed using Verilog-A is developed for hybrid BICMOS and photonic system-level simulation in integrated circuit (IC) design environment. Six sub-blocks of the Segmented-Electrode MZM in silicon photonic process platform are discussed and critical device functions of each sub-block is given. A good open eye diagram of the optical output power at 25 Gb/s data rate is shown in this paper as a co-simulation result. The transmitter's −3 dB bandwidth is 23 GHz. The whole Segmented-Electrode MZM transmitter achieves an extinction ratio of 9 dB.
