16-QAM modulation by polar coordinate transformation with a single dual drive Mach-Zehnder Modulator

16-QAM modulation by a single dual-drive Mach-Zehnder modulator with minimum drive voltage employing polar coordinate transformation instead of a vector I/Q modulator was demonstrated. Clear signal separation was observed with 6-bit DAC resolution.
