Scalable Multilevel oDAC-Based PAM-m | QAM-m2 Tx Using Just PAM-2|4 Electronic Drivers - Comparative Performance

Electronic DACs bottlenecks in high-speed transmission are eliminated by our recent optical-DAC based modulation scheme parallelizing two MZMs, for optical 64/256QAM generation, fed solely by NRZ or PAM-4 drivers yielding 3 to 8dB extra EVM margin.
