Research on the Controllable Frequency Octupling Technology for Generating Optical Millimeter-wave by External Modulator
A novel scheme is proposed for frequency octupling mm-wave generation based on an integrated triple-parallel MZM without filter.Two kinds of redundant sidebands are well eliminated by adopting 90 degrees of the electric phase-difference about two sub Mach-Zehnder modulators(sub-MZMs),driven by radio frequency(RF)signal.Then bias of the third sub-MZM is tailored to get best signal.The results indicate that the radio frequency spurious suppression ratio(RFSSR)is as high as 38.3315 dB under the condition of conventional extinction ratio(30 dB).Moreover,optical sideband suppression ratio(OSSR)can reach as high as 61.22878 dB at ideal extinction ratio(100 dB).Compared with previous schemes,it not only optimizes the method but get high RFSSR in the conventional condition.
