Generation of Square or Hexagonal 16-QAM Signals Using a Single Dual Drive IQ Modulator Driven by Binary Signals


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.
