Abstract :
A frequency quadrupling scheme for optical mm-wave signal generation is proposed and demonstrated based on dual-electrode dual-parallel integrated Mach-Zehnder modulator (MZM) consisting of three dual-electrodes MZMs. The electrical filters or optical filters are not required in this scheme. The theoretical analysis is presented to configurate the phases and DC biases of the integrated MZM. The simulation and experiment verification are both conducted to evaluate the performance of the proposed scheme. With 9GHz RF drive signal, the optical sideband suppression ratio (OSSR) higher than 35dB is demonstrated experimentally. The 36GHz mm-wave is generated with the RF spurious suppression ratio (RFSSR) over 30dB.
