Abstract

A photonic approach for frequency-sextupled microwave signal generation without filter or precise phase control is demonstrated by computer simulations and experiments. Without any filter, a frequency-sextupled microwave signal is generated by adjusting bias voltages of the cascade modulators. This structure largely reduces the dependence of particular phase relation that is built between the different modulated signals. The approach is verified by simulations and experiments, and stable 18- and 24-GHz frequency-sextupled signals are generated by 3 and 4 GHz local signals without filter or precise phase control.
