Optical 64‐QAM transmitter using QPSK modulators in tandem driven by binary electrical signals is proposed. The proposed transmitter eliminates the need for complex electronics required for the generation of multiple‐level signals and provides a Gray‐coded constellation with high quality eye diagrams. The design could be scaled to higher‐order QAM based on the user needs.
