Generation of square or hexagonal 16-QAM signals using a single dual drive IQ modulator driven by binary signals

Abstract

A simple square or hexagonal 16-QAM generation technique using a commercially available dual drive IQ modulator driven by 4 binary signals is proposed. Square or hexagonal polarization multiplexed (PM) 16-QAM signals at 25Gbaud/s are experimentally demonstrated.
