Abstract: In this study, we have demonstrated two schemes for the generation of millimeter-wave (mm-wave) using optical frequency sixupler with a dual-electrode modulator (MZM). For scheme one and scheme two, the phase of RF signal is shifted by 180 degrees, drives the two electrodes of MZM at different bias levels and then high order sidebands is removed by optical bandpass filter. Theoretical analysis and simulation results show that the performance of millimeter-wave for scheme two is better than that of scheme one.
