Photonic Generation for Frequency 12‐Tupling Millimeter‐Wave Signal Based on Three Parallel Polarization Modulators.

In the work, a new photonic generation method for frequency 12‐tupling millimeter‐wave (mm‐wave) signals is proposed. In the proposed scheme, only three parallel polarization modulators are used to generate the wanted optical sidebands. Then by properly controlling the modulation index and electrical phase shifters, the undesired optical sidebands can be canceled. The theoretical and simulation results of the optical sideband suppression ratio (OSSR) and radio frequency spurious suppression ratio (RFSSR) are 58.36dB, 57.30dB, and 52.39dB, 52.06dB, respectively. The simulation values are almost consistent with the theoretical analysis results, which proves that the proposed scheme is feasible. However, there may be errors in the parameters of those components that can affect the quality of the obtained signal. Thus, the impact of errors caused by these parameters on OSSR and RFSSR is analyzed and an acceptable range of error is listed. [ABSTRACT FROM AUTHOR]
