O-band DAC-less PAM-4 generation with a silicon dual-drive Mach-Zehnder Modulator

4-level pulse amplitude modulation (PAM-4) is the chosen modulation format for next generation optical short-reach data communications such as intra-datacenter communications. On-chip generation of PAM-4 signals is possible using a single dual-drive Mach-Zehnder modulator (MZM). By driving the modulator with two voltage-unbalanced binary signals it is possible to avoid any power hungry electrical digital-to-analog converter (DAC). PAM-4 signal generation at 20 Gbit/s is demonstrated using a silicon dual-drive MZM in the O-band. A bit error rate (BER) of 3.8.10-3 is measured at-6 dBm input power.
