Abstract

We propose experimentally a technique to generate a low noise frequency octupled microwave signal. We demonstrate that by carefully arranging the phase of 90° between two MZMs (out of three), a low noise photonically assisted octupled microwave signal can be generated. A 25.6 GHz optical microwave signal is achieved with 3.2 GHz of local RF oscillator signal. Moreover, the intensity expressions at the output of photodiode are derived for both with and without dispersion terms. Finally, we advocate the impact of the electrical spurious suppression ratio on the extinction ratio of the modulators. Our experimental and simulation results agree well with the theoretical analysis.
