“…The key technology about optical mm-wave generation is to simplify the base station and reduce system cost [2]. It is mm-wave communication [3][4][5][6][7][8] that is also one of the academic focuses, which has important application in the future communication, military and other fields. Schemes for generating mm-wave [9][10][11][12][13][14][15][16], based on the nonlinear of Mach-Zehnder modulator (MZM), have a very wide range of applications and have been extensively studied.…”

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.
