Systematic design and simulation methodology for hybrid optical transmitters that combine CMOS circuits in a 130 nm process, and a traveling-wave Mach-Zehnder modulator (TWMZM) in 130 nm SOI CMOS process, is presented. A compact Verilog-A model for the TWMZM is adopted for the electrooptical simulation. A bond wire model using a high-frequency solver is included for accurate package simulation. Transmitter post-layout simulation result exhibits 5.48 dB extinction ratio, 9.6 ps peak-to-peak jitter, and the best power efficiency of 5.81 pJ/bit when operating up to 12.5 Gb/s non-return-to-zero data. A pulse amplitude modulation 4-level transmitter with detailed linearity design procedure is presented which has horizontal and vertical eye opening of 49 ps and 203 μW when operating at 25 Gb/s, and the power efficiency is 5.09 pJ/bit.
