Generation of 64-QAM signals using a single dual-drive IQ modulator driven by 4-level and binary electrical signals

A simple square 64-QAM generation technique using a commercially available dual-drive IQ modulator driven by 4-level and binary electrical signals is proposed. Polarization multiplexed (PM) 64-QAM signals at 20Gbaud/s are experimentally demonstrated.
